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

Replace 95 lines of custom molecule instantiation with bd mol run:
- No more ephemeral beads layer
- No more manual molecule template handling
- bd mol run handles spawning, assignment, and pinning

Add isChildOfEpic() function that checks if an issue is a child of
the configured epic by verifying the issue has the epic in its
dependents with dependency_type="blocks".
When EpicID is configured in witness config, only issues that block
that epic will be considered for auto-spawning. Issues that cannot
be verified are safely skipped.
Closes gt-zhm5.

Remove RenderSuccess, RenderWarning, RenderError, and RenderInfo
functions that were never used. The codebase uses style.SuccessPrefix
and style.Success.Render() directly instead.

Implement DFS-based cycle detection in ValidateMolecule to catch
circular dependencies in molecule step graphs. The algorithm uses
three-color marking (unvisited/visiting/visited) to detect back
edges that indicate cycles.
When a cycle is detected, the error message shows the cycle path
(e.g., "a -> b -> c -> a") for easy debugging.
Add 4 new tests:
- SimpleCycle: A -> B -> A
- LongerCycle: A -> B -> C -> A
- DiamondNoCycle: ensures valid diamond patterns pass
- CycleInSubgraph: cycle not involving root node
Closes gt-ai1z.

Add getRig() helper in rig_helpers.go that encapsulates the common
boilerplate for finding town root, loading rigs config, and retrieving
a rig. This reduces duplication across 5 get*Manager functions:
- getPolecatManager
- getSessionManager
- getCrewManager
- getRefineryManager
- getWitnessManager
Closes gt-7sqi.

Two mechanisms, different purposes:
- Pinned molecule (bd mol run) = What you are working on, tracked by beads
- Handoff mail = Optional context notes for session restarts

Fixes gt-b6qm: redirect files can get deleted by git clean, causing
"no beads database found" errors.
Changes:
- crew.Manager.Add() now creates .beads/redirect during setup
- gt prime regenerates missing redirects silently on startup
The redirect points to the shared beads database at either:
- rig/mayor/rig/.beads/ (preferred)
- rig/.beads/ (fallback)

Adds gt peek as ergonomic alias for gt session capture:
gt peek gastown/furiosa # Last 100 lines
gt peek gastown/furiosa 50 # Last 50 lines
Creates nudge/peek pair as canonical session interface:
gt nudge - send TO session (reliable delivery)
gt peek - read FROM session (capture-pane wrapper)
Adds docs/session-communication.md explaining:
- Why raw tmux send-keys is unreliable for Claude
- The reliable NudgeSession pattern (literal + delay + Enter)
- Command reference and common patterns
- Guidance for template authors

Now accepts ergonomic rig/polecat addresses:
gt nudge gastown/furiosa "Check your mail"
Still supports raw session names for legacy use.

When polecat branches have .beads/ tracked from previous bd sync operations,
those files would contaminate the new worktree. Now setupSharedBeads():
1. Removes any existing .beads/ contents before creating redirect
2. Points redirect directly to mayor/rig/.beads (matches crew workers)
Also adds sling-design.md documenting the gt sling command design.

Principle covering:
- The One Rule (hook has work → work happens)
- Why it works (stateless agents, molecule-driven, beads as control plane)
- The sling lifecycle diagram (spawn → attach → execute → burn)
- Agent startup protocol (gt prime → check attachment → execute or wait)
- Propulsion patterns and anti-patterns
- Nondeterministic idempotence
