feat(maestro): scaffold Android project (Kotlin, Compose, Material 3)

Greenfield Gradle project under android/ — single-activity, Compose-only UI, Kotlin DSL + version catalog throughout. MainActivity shows a placeholder screen; no daemon connection yet (#262). minSdk 26, targetSdk 34. OkHttp and kotlinx-serialization-json wired in for the upcoming daemon client. Debug signing config uses a committed debug.keystore so the APK installs without extra setup.

 ## Where the work is

-Linear project **Maestro** under team **Naps62**.
+Gitea issues on [`naps62/maestro`](https://git.naps.pt/naps62/maestro), grouped
+into milestones.

+`.claude/linear.json` (legacy filename, `tracker: gitea`) wires `/yolo` and
+`/work` to that tracker — they pick from open, unassigned issues whose
+dependencies are all closed. `/blitz <milestone>` sweeps a whole milestone.
+
+Labels carry one value per axis: `area/*`, `type/*`, `difficulty/*`.
+`difficulty` drives model selection downstream, so it tracks the shape of the
+work, not its size.

+#   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/.

+#!/usr/bin/env python3
+"""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)

+                            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).

+//! 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.

+//! What size the shared tmux window should be, given every client watching it.
+//!
+//! A tmux window has one size, but a session can have several clients attached
+//! at once — two browser panes, a browser and the TUI. Each reports the size
+//! *it* can display, and applying whichever arrived last makes the window
+//! flip-flop. Every flip forces a full-screen application (Claude Code, vim) to
+//! repaint at a new height, and the rows it drew at the old height are never
+//! cleared: the operator ends up looking at a stale input box, types into a
+//! box that is not where the screen says it is, and concludes the pane is
+//! stuck.
+//!
+//! So the window is sized to the smallest attached client on each axis — the
+//! same rule tmux uses for its own multiple clients, and the only size every
+//! client can render without truncation. The size last handed to tmux is
+//! remembered, so a report that changes nothing costs no `tmux` fork at all.
