* 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. Closes: gt-xh2bh Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * 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.
