* perf(tmux): batch session queries in gt down to reduce N+1 subprocess calls
Add SessionSet type to tmux package for O(1) session existence checks.
Instead of calling HasSession() (which spawns a subprocess) for each
rig/session during shutdown, now calls ListSessions() once and uses
in-memory map lookups.
Changes:
- internal/tmux/tmux.go: Add SessionSet type with GetSessionSet() and Has()
- internal/cmd/down.go: Use SessionSet for dry-run checks and session stops
- internal/session/town.go: Add StopTownSessionWithCache() variant
- internal/tmux/tmux_test.go: Add test for SessionSet
With 5 rigs, this reduces subprocess calls from ~15 to 1 during shutdown
preview, saving 60-150ms of execution time.

* perf(tmux): optimize SessionSet to avoid intermediate slice allocation
- Build map directly from tmux output instead of calling ListSessions()
- Use strings.IndexByte for efficient newline parsing
- Pre-size map using newline count to avoid rehashing
- Simplify nil checks in Has() and Names()
* fix(sling): restore bd cook directory context for formula-on-bead mode
The bd cook command needs to run from the target rig's directory to
access the correct formula database. This was accidentally removed
in a previous commit, causing TestSlingFormulaOnBeadRoutesBDCommandsToTargetRig
to fail.

Add comprehensive crash logging improvements to help diagnose mass session death events:
- Add TypeSessionDeath and TypeMassDeath event types for feed visibility
- Log pre-death events before killing sessions (who killed, why)
- Add mass death detection in daemon (3+ deaths in 30s triggers alert)
- Add macOS crash report check in gt doctor
- Support session death events in townlog and feed curator

Town-level services (Mayor, Deacon) now use hq- prefix instead of gt-:
- hq-mayor (was gt-mayor)
- hq-deacon (was gt-deacon)
This distinguishes town-level sessions from rig-level sessions which
continue to use gt- prefix (gt-gastown-witness, gt-gastown-crew-max, etc).
Changes:
- session.MayorSessionName() returns "hq-mayor"
- session.DeaconSessionName() returns "hq-deacon"
- ParseSessionName() handles both hq- and gt- prefixes
- categorizeSession() handles both prefixes
- categorizeSessions() accepts both prefixes
- Updated all tests and documentation

Previously, town-level session stopping (Mayor, Boot, Deacon) was
implemented inline in gt down with separate code blocks for each
session. The shutdown order (Boot must stop before Deacon to prevent
the watchdog from restarting Deacon) was implicit in the code ordering.
Add session.TownSessions() and session.StopTownSession() to centralize
town-level session management. This provides a single source of truth
for the session list, shutdown order, and graceful/force logic.
Refactor gt down to use these helpers instead of inline logic.
