Add a `spawn_history` daemon module backing the spawn form's "recent dirs"
picker. Sidecars are deleted on kill, so they can't be the source — use an
append-only JSONL log at `<state_dir>/spawn-history.jsonl`, one record per
successful spawn (cwd, command, name, worktree_branch, at).
- Write: `SessionManager::create` appends after a successful spawn,
best-effort — a log-write failure only warns, never fails the spawn.
- Read: `recent_dirs()` folds newest-first, dedups by cwd, drops entries past
the recency cap, caps the result count.
- Prune: opportunistic `compact()` from `append` once the file passes a size
threshold; atomic tmp+rename rewrite.
- Config: `[daemon].spawn_history_days` (default 30, `0` disables). History is
wired into the manager at daemon startup.
Time-dependent logic is factored into `*_as_of(now)` helpers for
deterministic unit tests. Adds module unit tests (append/dedup/recency
prune/compaction/disabled/malformed/cap), a config resolution test, and
real-tmux integration tests proving create→append→read end to end.

Completes the headless daemon stack for NAP-214.
- `config`: daemon TOML config (daemon_id, registry_url, bind_addr,
token, state_dir, worktree_root) with sensible XDG defaults.
- `jwt`: HS256 verifier; the daemon validates per-attach JWTs locally
with no callback to the registry. Also exposes `issue()` for tests.
- `pty::PtyBridge`: per-session FIFO + tokio broadcast pump. The FIFO is
opened r+w so it never sees zero writers — stays alive across
`pipe-pane` re-issues. Helper `pipe_pane_command()` builds the
`cat >> <fifo>` shell line.
- `session::SessionManager`: authoritative live-session store. Creates
worktrees (when requested), spawns tmux, mkfifo + pipe-pane, writes
sidecar; tears it all down on kill. Emits diff events on a
broadcast for the registry client. `recover()` adopts surviving
`maestro-*` tmux sessions on startup and re-pipes them.
- `registry_client::RegistryClient`: persistent outbound WS to the
registry with exponential backoff. Sends Hello → snapshot, drives a
select loop that pumps inbound CreateSession/KillSession RPCs into
the manager (replying with results), emits SessionAdded/Removed/
Updated diffs from the manager, and heartbeats every 10s.
- `attach`: axum router mounting `WS /sessions/:id/stream?token=<jwt>`.
Binary frames carry PTY bytes either way (subscribe to broadcast →
send to client; receive from client → tmux send-keys -l). Text
frames carry `ClientControl::{Resize,Ping,Pong}`.
- `bin/maestrod`: ties everything together, loads config from
`MAESTROD_CONFIG` env or `~/.config/maestrod/config.toml`,
recovers, spawns the registry client, binds the WS server.
Also adds `JwtClaims` to `maestro-protocol` so the daemon and the
future registry JWT issuer (NAP-215) agree on the wire shape.
Integration tests cover session manager round-trip + recovery + PTY
broadcast; attach endpoint JWT (bad/wrong-session/wrong-daemon),
PTY round-trip through real tmux, multi-attach broadcast, ping/pong;
registry client registration + snapshot + diff forwarding +
CreateSession RPC round-trip.
Closes NAP-214.
Local primitives for `maestrod`, no network code yet:
- `tmux`: subprocess wrapper around new-session, kill-session,
list-sessions (filtered to maestro-*), send-keys -l, pipe-pane -o,
resize-window, kill-server.
- `sidecar`: atomic JSON metadata store keyed by session UUID, with
load_all for daemon restart recovery.
- `worktree`: `git worktree add -b` with collision-proof generated paths
and `git worktree remove --force` for cleanup_on_kill.
Integration tests use real tmux (isolated via unique socket + temp
TMUX_TMPDIR) and real git (tmpdir repo).
Closes NAP-212.
