Architecture changes:
- Refinery created as worktree of mayor clone (shares .git)
- Polecat branches stay local (never pushed to origin)
- MRs stored as wisps in .beads-wisp/mq/ (ephemeral)
- Only main gets pushed to origin after merge
New mrqueue package for wisp-based MR storage.
Updated spawn, done, mq_submit, refinery, molecule templates.

- Create internal/claude package with embedded settings templates
- settings-autonomous.json: gt prime && gt mail check --inject (SessionStart)
- settings-interactive.json: gt prime only (SessionStart)
- Update witness.go: EnsureSettings before session, remove broken gt prime injection
- Update refinery/manager.go: EnsureSettings before session, remove broken NudgeSession
- Update session/manager.go: EnsureSettings for polecats, remove broken issue injection
All autonomous roles (polecat, witness, refinery) now get proper SessionStart hooks
automatically when their sessions are created. No more timing-based gt prime injection.
Wait for Claude to start before sending the prime command, and use
NudgeSession (with 500ms debounce) instead of SendKeysDelayed for
reliable message delivery.

Add output field (io.Writer) to Manager and Engineer structs with
SetOutput() methods to enable testability and output redirection.
Replace all 30+ fmt.Printf/Println calls with fmt.Fprintf/Fprintln
using the configurable output writer, defaulting to os.Stdout.
This enables:
- Testing output without capturing stdout
- Redirecting output in different contexts
- Following cobra best practices

- Add refinery and crew to identityToStateFile()
- Fix gt refinery start to send gt prime after Claude starts
- New syncWorkspace() helper for agents with persistent clones
In foreground mode, skip the tmux session check since we are likely
running inside the session that background mode created. Only check
PID to avoid self-detection.
Fixes the issue where gt refinery start gastown --foreground would
detect its own tmux session as already running.

The Refinery now runs as a Claude agent in a tmux session instead of
a Go-based polling loop. This aligns it with how polecats work and
enables intelligent MR processing.
Changes:
- Modified refinery.Start() to spawn Claude session (not gt refinery --foreground)
- Added gt refinery attach command for interactive access to refinery session
- Updated refinery.md.tmpl with comprehensive Claude agent instructions
- Added startup directive in gt prime for refinery role
The --foreground mode is preserved for backwards compatibility but the
default behavior now launches a Claude agent that can review diffs,
run tests, handle conflicts, and notify workers via mail.

Replace branch discovery with Beads queue in Engineer:
- ProcessMR: full merge execution (fetch, conflict check, merge, test, push)
- handleSuccess: close MR and source issue, notify worker
- handleFailure: reopen MR, assign to worker, send failure notification
- Helper functions: gitRun, gitOutput, runTests, pushWithRetry, checkConflicts
The Engineer now:
- Polls for merge-requests via bd ready --type=merge-request
- Claims MRs by setting status to in_progress
- Processes merges with conflict detection and test execution
- Closes MRs and source issues on success
- Assigns back to workers on failure with appropriate notifications

Implement success handling for the merge queue Engineer:
- Add handleSuccess method that handles successful merge completion
- Update MR body with merge_commit SHA and close_reason
- Close MR with 'merged' reason
- Close source issue with reference to MR ID
- Delete source branch if delete_merged_branches is configured
- Add DeleteRemoteBranch method to git package
- Add git client to Engineer struct
- Add tests for new functionality

Implement the actual merge execution in Engineer.ProcessMR:
- ExecuteMerge function: checkout target, merge with --no-ff, run tests
- pushWithRetry: exponential backoff retry logic (3 retries, 1s base delay)
- runTests: execute configurable test command
- gitRun/gitOutput: helper methods for git operations
When tests fail, resets to HEAD~1 before returning failure.
When push fails after retries, resets to HEAD~1 before returning failure.
Conflict detection during merge triggers automatic merge --abort.

Add tmux status bar theming for Gas Town sessions:
- Per-rig color themes auto-assigned via consistent hashing
- 10 curated dark themes (ocean, forest, rust, plum, etc.)
- Special gold/dark theme for Mayor
- Dynamic status line showing current issue and mail count
- Mayor status shows polecat/rig counts
New commands:
- gt theme --list: show available themes
- gt theme apply: apply to running sessions

- gt status-line: internal command for tmux refresh
Status bar format:
- Left: [rig/worker] role

- Handle mail router.Send returns
- Handle os.RemoveAll, os.Rename in cleanup paths
- Handle rand.Read returns for ID generation

The refinery start command was only updating state.json without
actually starting a session. Now it spawns a tmux session named
gt-{rig}-refinery that runs the refinery in foreground mode.
Also updated Stop() and Status() to properly check tmux session
state alongside the PID-based tracking for backwards compatibility.

Adds the Engineer component that polls for ready merge-requests and
processes them according to the merge queue design.
Features:
- Main loop that queries `bd ready` for merge-request type issues
- Configurable poll_interval and max_concurrent from rig config.json
- Graceful shutdown via context cancellation or Stop() method
- Claims MRs via `bd update --status=in_progress` before processing
- Handles success/failure with appropriate status updates
Configuration (in rig config.json merge_queue section):
- poll_interval: duration string (default "30s")
- max_concurrent: number (default 1)
- enabled, target_branch, run_tests, test_command, etc.
Also adds ReadyWithType() to beads package for type-filtered queries.
Note: ProcessMR() and handleFailure() are placeholders - full
implementation in gt-3x1.2 and gt-3x1.4.
