test: add comprehensive unit tests for all core services
Add vitest test suite with 103 tests across 5 test files:
- metadata.test.ts (19 tests): read/write/update/delete/list, key=value
parsing, comments, values with equals signs, archiving, dotfile exclusion
- event-bus.test.ts (22 tests): emit/on/off, wildcard listeners, handler
error resilience, priority inference, JSONL persistence round-trip,
filtered history with sessionId/projectId/type/priority/since/limit
- tmux.test.ts (23 tests): all tmux wrappers with mocked child_process,
session listing/parsing, send-keys short vs load-buffer long text,
capture-pane, kill, getPaneTTY
- session-manager.test.ts (23 tests): spawn pipeline with mocked plugins,
session numbering, branch derivation, event emission, metadata writing,
list with dead runtime detection, kill with cleanup, send via runtime
- lifecycle-manager.test.ts (16 tests): state transitions (spawning→working,
killed, stuck, needs_input, ci_failed, merged, mergeable), reaction
triggering, auto=false suppression, on/off handlers, getStates isolation
Also fixes inferPriority to handle merge.completed as "action" priority.
