Subhrajit Makur 6a705f6210 Feat/gt down tests (#15) (#18) (#330)
* fix(down): add refinery shutdown to gt down

Refineries were not being stopped by gt down, causing them to continue
running after shutdown. This adds a refinery shutdown loop before
witnesses, fixing problem P3 from the v2.4 proposal.

Changes:
- Add Phase 1: Stop refineries (gt-<rig>-refinery sessions)
- Renumber existing phases (witnesses now Phase 2, etc.)
- Include refineries in halt event logging

* feat(beads): add StopAllBdProcesses for shutdown

Add functions to stop bd daemon and bd activity processes:
- StopAllBdProcesses(dryRun, force) - main entry point
- CountBdDaemons() - count running bd daemons
- CountBdActivityProcesses() - count running bd activity processes
- stopBdDaemons() - uses bd daemon killall
- stopBdActivityProcesses() - SIGTERM->wait->SIGKILL pattern

This solves problems P1 (bd daemon respawns sessions) and P2 (bd activity
causes instant wakeups) from the v2.4 proposal.

* feat(down): rename --all to --nuke, add new --all and --dry-run flags

BREAKING CHANGE: --all now stops bd processes instead of killing tmux server.
Use --nuke for the old --all behavior (killing the entire tmux server).

New flags:
- --all: Stop bd daemons/activity processes and verify shutdown
- --nuke: Kill entire tmux server (DESTRUCTIVE, with warning)
- --dry-run: Preview what would be stopped without taking action

This solves problem P4 (old --all was too destructive) from the v2.4 proposal.

The --nuke flag now requires GT_NUKE_ACKNOWLEDGED=1 environment variable
to suppress the warning about destroying all tmux sessions.

* feat(down): add shutdown lock to prevent concurrent runs

Add Phase 0 that acquires a file lock before shutdown to prevent race
conditions when multiple gt down commands are run concurrently.

- Uses gofrs/flock for cross-platform file locking
- Lock file stored at ~/gt/daemon/shutdown.lock
- 5 second timeout with 100ms retry interval
- Lock released via defer on successful acquisition
- Dry-run mode skips lock acquisition

This solves problem P6 (concurrent shutdown race) from the v2.4 proposal.

* feat(down): add verification phase for respawn detection

Add Phase 5 that verifies shutdown was complete after stopping all services:
- Waits 500ms for processes to fully terminate
- Checks for respawned bd daemons
- Checks for respawned bd activity processes
- Checks for remaining gt-*/hq-* tmux sessions
- Checks if daemon PID is still running

If anything respawned, warns user and suggests checking systemd/launchd.

This solves problem P5 (no verification) from the v2.4 proposal.

* test(down): add unit tests for shutdown functionality

Add tests for:
- parseBdDaemonCount() - array, object with count, object with daemons, empty, invalid
- CountBdActivityProcesses() - integration test
- CountBdDaemons() - integration test (skipped if bd not installed)
- StopAllBdProcesses() - dry-run mode test
- isProcessRunning() - current process, invalid PID, max PID

These tests cover the core parsing and process detection logic added
in the v2.4 shutdown enhancement.

* fix(review): add tmux check and pkill fallback for bd shutdown

Address review gaps against proposal v2.4 AC:

- AC1: Add tmux availability check BEFORE acquiring shutdown lock
- AC2: Add pkill fallback for bd daemon when killall incomplete
- AC2: Return remaining count from stop functions for error reporting
- Style: interface{} → any (Go 1.18+)



* fix(prime): add validation for --state flag combination

The --state flag should be standalone and not combined with other flags.
Add validation at start of runPrime to enforce this.

Fixes TestPrimeFlagCombinations test failures.

* fix(review): address bot review critical issues

- isProcessRunning: handle pid<=0 as invalid (return false)
- isProcessRunning: handle EPERM as process exists (return true)
- stopBdDaemons: prevent negative killed count from race conditions
- stopBdActivityProcesses: prevent negative killed count from race conditions



* fix(review): critical fixes from deep review

Platform fixes:
- CountBdActivityProcesses: use sh -c "pgrep | wc -l" for macOS compatibility
  (pgrep -c flag not available on BSD/macOS)

Correctness fixes:
- stopSession: return (wasRunning, error) to distinguish "stopped" vs "not running"
- daemon.IsRunning: handle error instead of ignoring with blank identifier
- stopBdDaemons/stopBdActivityProcesses: guard against negative killed counts

Safety fixes:
- --nuke: require GT_NUKE_ACKNOWLEDGED=1, don't just warn and proceed
- pkill patterns: document limitation about broad matching

Code cleanup:
- EnsureBdDaemonHealth: remove unused issues variable
