feat(maestro): wire DaemonLink into MainActivity, allow cleartext traffic

Reads the EXTRA_DAEMON_URL intent extra, starts DaemonLink, and shows its LinkState in the placeholder screen so the connection indicator has something to bind to. usesCleartextTraffic is required for the daemon's plain-HTTP LAN endpoint; ACCESS_NETWORK_STATE is required for ConnectivityManager.registerNetworkCallback.

 work, not its size.

 See `docs/INSTALL.md` for end-user install instructions.
 `docs/WORKTREES.md` is the contract for session worktrees — placement,
 collisions, what blocks a kill, and what `--force` leaves behind. Read it
 before changing anything that creates or removes one.
 `docs/SIDEBAR.md` is the contract for session cards in the web and TUI
 sidebars — line layout, activity colours, duration format, state precedence.
 Read it before changing sidebar rendering.
 `docs/PREVIEW.md` is the contract for what the content pane shows while the
 operator moves the sidebar highlight — what a preview may touch, what ends it,
 what commits it. Read it before changing sidebar-driven navigation.
 `docs/RESTART.md` is the contract for what clients do when the daemon restarts
 or is upgraded under them — the build stamp on `/api/info`, the status
 indicator's states, the blocking overlay, grace and poll timings. Read it
 before changing reconnect behaviour on either client.
 `docs/COMMAND-BAR.md` is the contract for the `ctrl-k` command bar in both
 clients — how it opens, the sigils, the key model, the match-and-rank algorithm
 the two matchers must agree on, and the fixture table they are tested against.
 Read it before changing either bar or either matcher.
 `docs/STRUCTURED-VIEW.md` is the contract for a structured session (an agent
 run as a daemon child over ACP instead of in a tmux pane) — the eight
 transcript row kinds, the two projections and their cursor/replay semantics,
 the handshake and declined capabilities, and the approval nonce rules. Read
 it before changing anything that renders a structured session.
 `nix run .#dev` (or `just dev`) brings up the whole local stack under
 process-compose: a debug daemon on 127.0.0.1:7071, then Vite on :5173 once the
 daemon answers `/api/info`. The SPA proxies `/api/*` back to the daemon, so only
 the UI is exposed on the network. The dev port is deliberately not the daemon's
 own default 7070 (`devDaemonPort` in `flake.nix`), so the stack never fights a
 real daemon on the same host.

 #
 #   Gradle start up script for POSIX generated by Gradle.
 #
 #   Important for running:
 #
 #   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
 #       noncompliant, but you have some other compliant shell such as ksh or
 #       bash, then to run this script, type that shell name before the whole
 #       command line, like:
 #
 #           ksh Gradle
 #
 #       Busybox and similar reduced shells will NOT work, because this script
 #       requires all of these POSIX shell features:
 #         * functions;
 #         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
 #           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
 #         * compound commands having a testable exit status, especially «case»;
 #         * various built-in commands including «command», «set», and «ulimit».
 #
 #   Important for patching:
 #
 #   (2) This script targets any POSIX shell, so it avoids extensions provided
 #       by Bash, Ksh, etc; in particular arrays are avoided.
 #
 #       The "traditional" practice of packing multiple parameters into a
 #       space-separated string is a well documented source of bugs and security
 #       issues, so this is (mostly) avoided, by progressively accumulating
 #       options in "$@", and eventually passing that to Java.
 #
 #       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
 #       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
 #       see the in-line comments for details.
 #
 #       There are tweaks for specific operating systems such as AIX, CygWin,
 #       Darwin, MinGW, and NonStop.
 #
 #   (3) This script is generated via the Gradle "wrapper" task
 #       (see https://docs.gradle.org/current/userguide/gradle_wrapper.html)
 #       within the Gradle project.
 #
 #       You can find Gradle at https://github.com/gradle/gradle/.

 """A deterministic stand-in for `claude-code-acp` (#134).
 Speaks just enough JSON-RPC over stdio for the daemon's handshake:
 answers `initialize` and `session/new`, logs every method it receives, and
 exits on SIGTERM. Tests point `PATH` at a directory holding this file under
 the adapter's name, so the real adapter (which needs Claude auth and is
 slow) never runs in the deterministic suite.
 Environment knobs, all optional:
  FAKE_ACP_LOG            append one line per event to this file:
                            start pid=<pid> cwd=<cwd>
                            env <NAME>=<value>       (for FAKE_ACP_ECHO_ENV)
                            caps <json of clientCapabilities>
                            recv <method>
                            signal SIGTERM
  FAKE_ACP_ECHO_ENV       name of one env var to log at start
  FAKE_ACP_INIT_FAIL=1    answer `initialize` with a JSON-RPC error
  FAKE_ACP_DELAY_SESSION_NEW_MS=n  wait n milliseconds before answering
                             `session/new`
  FAKE_ACP_SESSION_NEW_GATE=path  wait for `path` to exist before answering
                             `session/new`
  FAKE_ACP_EXIT_AFTER_NEW=1  exit 0 right after answering `session/new`
  FAKE_ACP_EXIT_ON_CANCEL=1  exit 0 on `session/cancel` (default: keep running
                             so the SIGTERM path is exercised)
  FAKE_ACP_IGNORE_EOF=1      keep running after stdin closes, until signalled
  FAKE_ACP_EMIT_ON_CANCEL=1  emit a final notification before handling cancel
  FAKE_ACP_CANCEL_SETTLES=1  complete the outstanding prompt on cancel
  FAKE_ACP_NO_LOAD=1      advertise `loadSession: false`
  FAKE_ACP_LOAD_REPLAY=n  on `session/load`, replay n `agent_message_chunk`
                            notifications ("replayed <i>") before answering,
                            the way a real agent streams history back
  FAKE_ACP_LOAD_FAIL=1    answer `session/load` with a JSON-RPC error
  FAKE_ACP_DELAY_PROMPT_MS=n  wait before answering `session/prompt`
  FAKE_ACP_PROMPT_FAIL=1  answer every `session/prompt` with a JSON-RPC error
  FAKE_ACP_PROMPT_FAIL_ONCE=1  answer only the first `session/prompt` with a
                             JSON-RPC error
  FAKE_ACP_SETTINGS=1      advertise legacy model/mode and modern effort options
  FAKE_ACP_PERMISSION_AFTER_CANCEL=1  defer the first prompt's permission
                             callback until a later prompt
 Signals: SIGUSR1 emits one `agent_message_chunk` notification ("tick <n>",
 counting from 1) and logs `emit tick <n>`, so a test can make the agent
 speak on demand (#135).

 //! Two build-time jobs for the daemon.

 //! sources, in order:
 //!
 //! 1. `MAESTRO_BUILD_COMMIT` / `MAESTRO_BUILD_DATE` / `MAESTRO_BUILD_DIRTY` in
 //!    the environment. The Nix build has no `.git` in its source tree (crane
 //!    filters it out), so `flake.nix` passes the flake's own revision this way.
 //! 2. The git checkout the crate is being compiled in.
 //!
 //! Neither available leaves the values empty; clients treat that as "unknown
 //! release" rather than an error.
 //!
 //! **SPA bundle.** Under the `web` feature only, resolve the directory
 //! `static_bundle.rs` embeds via `include_dir!` and publish it as
 //! `MAESTRO_WEB_BUNDLE_DIR`. Two modes:
 //!
 //! * `MAESTRO_WEB_DIST` set — the bundle was built elsewhere (Nix, CI, a
 //!   release pipeline) and that directory is embedded as-is. No node, no pnpm.
 //! * unset — the default developer path: run `pnpm install --frozen-lockfile
 //!   && pnpm build` in `web/` and embed `web/dist`. pnpm and node are HARD
 //!   requirements here; a missing toolchain fails with an actionable message
 //!   rather than silently shipping the placeholder.

 //! Naming a session after its first prompt (#131).

 //! The first prompt an agent reports to `POST /api/sessions/:id/prompt`
 //! replaces it with a name derived from that prompt, and the session settles
 //! at [`NameSource::Haiku`]. Only the first prompt does this: a session names
 //! itself once.
 //!
 //! The name is produced by running `claude -p --model haiku` on this machine —
 //! the daemon has no API key, makes no outbound HTTP request, and reuses
 //! whatever authentication the operator's own CLI already has. Everything here
 //! is best-effort: a missing binary, a timeout, or an unusable answer leaves
 //! the generated handle in place.
 //!
 //! The prompt is a user's own text, and it is handled as data throughout. It
 //! goes to the child on stdin (never argv, where it would be visible in the
 //! process table), it is never logged, and whatever comes back is reduced to
 //! a short slug by [`clean`] rather than trusted as a name.

 //! Project discovery for `GET /api/projects` (#54).
 //!
 //! Scans `[spawn].project_roots` (default the whole home) for `.git` entries —
 //! directory or file, so linked worktrees count too — up to
 //! `[spawn].project_scan_depth` levels. Descent stops at the first repo found:
 //! nested independent repos are not discovered, but worktrees of every hit
 //! still are, via `git worktree list`, which also catches linked worktrees
 //! living outside the roots.
 //!
 //! Hidden directories are skipped everywhere; heavy well-known directories
 //! (`node_modules`, `Downloads`, …) are skipped when they sit directly in the
 //! home directory, so scanning all of home stays cheap.
 //!
 //! Results are cached behind a short TTL and refreshed on a slow background
 //! timer ([`ProjectScanner::start_background_refresh`]) — repositories appear
 //! rarely, and `/api/projects` may be polled.
