Adds ability to override embedded role templates at town or rig level:
- Town: <townRoot>/templates/roles/<role>.md.tmpl
- Rig: <rigPath>/templates/roles/<role>.md.tmpl
Rig-level overrides take precedence over town-level.
This enables customizing polecat (or other role) behavior per-rig without
modifying gastown source, following the same 3-tier override pattern as
role configs.
New APIs:
- NewWithOverrides(townRoot, rigPath string) - loads templates with overrides
- HasRoleOverride(role string) bool - check if role has override
- RoleOverrideCount() int - count of loaded overrides

Allow `gt crew status <rig>` to work without requiring --rig flag.
This matches the pattern already used by crew start and crew stop.

Extract prime.go into focused files:
- prime_session.go: session ID handling, hooks, persistence
- prime_output.go: all output/rendering functions
- prime_molecule.go: molecule workflow context
- prime_state.go: handoff markers, session state detection
Main prime.go now ~730 lines with core flow visible as "table of contents".
No behavior changes - pure file organization following Go idioms.
