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.

CI runs as root, where the 0o500 read-only sidecar dir doesn't block the
write the test relies on failing — so it reported a spurious failure and
has reddened main since commit 149. Probe writability and skip when root;
non-root runs still assert the rollback.
create() ran worktree-add → tmux spawn → sidecar write with no unwinding. A
failure in a later step leaked earlier ones — worst case a sidecar write
failure (disk full / EIO / permission) left a ghost `maestro-<uuid>` tmux
session running with no in-memory record, silently adopted with empty metadata
on the next daemon restart.
Each step now unwinds the ones before it: bridge/tmux failures remove the
worktree (+ FIFO), and a sidecar-write failure kills the just-spawned tmux
session before removing the FIFO + worktree.

`SessionManager::recover()` re-inserted each sidecar's `Session` verbatim,
keeping the persisted `daemon_id`. If the operator renamed the daemon between
starts, recovered sessions were re-advertised under the old id and became
unroutable. Overwrite `daemon_id` with the daemon's current id on recover,
warning when the sidecar's id differs.

`SessionManager::create` used to call `tmux new-session` (which exec's the
user's command immediately), run an async `PtyBridge::start_with_replay`
(mkfifo + open + spawn reader), then issue a *separate* `tmux pipe-pane`.
Any output the child wrote between exec and that third tmux subprocess
landing went into the pane but never into the FIFO. Hit in NAP-252
dogfood: `bash -c 'echo X; exec bash'` sessions showed only the trailing
prompt, never the X.
Two changes:
1. New `Tmux::new_session_piped(id, cwd, cmd, sink)` chains
`; pipe-pane -t maestro-<id> <sink>` into the same tmux command argv
as `new-session`. Within a tmux command chain, `pipe-pane` is
processed immediately after `new-session` returns — before the child
has finished `execve` — so the FIFO is wired up before the first
write.
2. `SessionManager::create` now builds the FIFO + reader task **before**
spawning the session, then calls `new_session_piped` instead of the
two-step `new_session` + `pipe_pane`.
`Tmux::pipe_pane` and the standalone `Tmux::new_session` stay around —
`recover()` (NAP-228) still needs a standalone pipe-pane re-attach, and
some integration tests want a bare session without a pipe.
Tests:
- Unit: argv assertion that the chained `pipe-pane` follows `new-session`
when a sink is supplied.
- Integration: `create_captures_initial_output_in_replay_buffer` spawns
`sh -c 'echo NAP_253_FIRST_LINE_MARKER; exec sleep 30'` and polls
`subscribe_pty_with_replay` until the marker shows up in the replay
buffer (or fails after 5s). Fails before the fix, passes after.

Capture sidecar_dir/fifo_dir/tmux/worktree_root before `drop(fx.manager)`
so the post-drop builder calls don't need to reborrow the partially-moved
fixture. Pure compile fix — same scenario as before.

`Tmux::pipe_pane` used `tmux pipe-pane -o`, which tmux documents as "only
open a new pipe if no previous pipe exists." When `maestrod` restarts and
`SessionManager::recover` re-issues `pipe-pane` against the adopted tmux
session, the previous daemon process's pipe to a now-orphan FIFO is
still active — so `-o` makes the call a no-op. The revived manager's
PtyBridge reads from a fresh FIFO that tmux never feeds, and attach
clients see input land in the pane but no output flow back.
Drop the `-o`. tmux closes any existing pipe before opening the new one,
which is what `pipe_pane` callers always wanted: `create` runs on a
fresh session (nothing to clobber), `recover` actively needs the
clobber.
Test: `recover_re_pipes_pane_so_output_reaches_subscribers` creates a
bash session under one manager, drops it, recovers under a second
manager, sends keys, and asserts the echo bytes reach a fresh
subscriber within 5s. Fails before the fix (stale pipe), passes after.

The daemon never noticed when a session's command exited and tmux tore
the session down — the in-memory `SessionManager` map plus the registry
catalog kept showing it as `Running`, and a follow-up `maestro attach`
would hang on an empty broadcast.
Adds a per-host background task that polls `tmux list-sessions` every
2s, diffs against the in-memory set, and reaps anything we still track
but tmux has lost: drops the record, deletes the sidecar + FIFO,
cleans up its worktree if requested, and emits `SessionEvent::Removed`
so the registry purges its catalog.
The task holds a `Weak<Inner>` so it exits cleanly once the last
`SessionManager` clone is dropped. Skips the tmux subprocess when the
in-memory map is empty.
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.
