fix(priming): use bootstrap pointers instead of full CLAUDE.md templates

Fresh installs and rig adds were creating full CLAUDE.md files (285 lines
for mayor, ~100 lines for other roles), causing gt doctor to fail the
priming check immediately.

Per the priming architecture, CLAUDE.md should be a minimal bootstrap
pointer (<30 lines) that tells agents to run gt prime. Full context is
injected ephemerally at session start.

Changes:
- install.go: createMayorCLAUDEmd now writes 12-line bootstrap pointer
- manager.go: createRoleCLAUDEmd now writes role-specific bootstrap pointers
  for mayor, refinery, crew, and polecat roles

Note: The AGENTS.md issue mentioned in #316 could not be reproduced - the
code does not appear to create AGENTS.md at rig level. May be from an older
version or different configuration.

Partial fix for #316
