test(fleet): hermetic heartbeat tests — temp run-dir + no leaked sidecars

ci/woodpecker/pr/ci Pipeline was successful

Details

ci/woodpecker/push/ci Pipeline was successful

Details

Tests 3, 4, 5 previously returned synthetic pane PIDs (99999/99998/99997)
from their fake list-panes shims but did not set MOSAIC_HEARTBEAT_RUN_DIR,
causing the launcher to fall back to the real ~/.config/mosaic/fleet/run
and potentially spawn a background sidecar against an arbitrary host PID.

Fix:
- list-panes in tests 3/4/5 now returns empty string → PANE_PID stays
  unset → no sidecar is spawned for tests where heartbeat is not under test.
- MOSAIC_HEARTBEAT_RUN_DIR is exported to a per-test mktemp dir in each
  fake-tmux test (3, 4, 5) as defence-in-depth so even if the sidecar
  code path changes, it can never write to the real fleet run dir.
- New temp dirs are registered in CLEANUP_DIRS so they are removed by the
  existing EXIT trap.
- Tests 6 and 7 (the dedicated heartbeat tests) are unchanged: test 6 uses
  a real tmux pane PID + its own HB_RUN_DIR, test 7 intercepts via a fake
  setsid shim that captures args and exits immediately.
- All 7 tests pass; verify-sanitized.sh passes; no stray sidecar processes
  or unexpected .hb files are written to ~/.config/mosaic/fleet/run.

feat(fleet): launcher heartbeat sidecar — HB for all runtimes (pi/claude/codex)

ci/woodpecker/push/ci Pipeline was canceled

Details

ci/woodpecker/pr/ci Pipeline was canceled

Details

Replace the terminal `exec tmux` with a plain `tmux new-session -d` so the
launcher continues running after creating the pane. The script then resolves
the pane PID via `tmux list-panes -F '#{pane_pid}'` (with a brief retry loop)
and spawns a detached, runtime-agnostic heartbeat sidecar via `setsid bash -c
... &` + `disown`. The sidecar loops while `kill -0 <pane_pid>` succeeds,
writing ~/.config/mosaic/fleet/run/<AGENT>.hb atomically (tmp + mv) every
MOSAIC_HEARTBEAT_INTERVAL seconds (default 15), then exits naturally when the
runtime process dies — making `mosaic fleet ps` show stale then dead.
HB_RUN_DIR and interval are configurable via env; sidecar startup is
best-effort (failures warn but do not abort the launch). Two new shell tests
cover pane-PID resolution (test 6, real tmux) and sidecar invocation
correctness (test 7, fake-tmux + fake-setsid shims).
