feat(session): Add GUPP to non-polecat roles (Mayor, Deacon, Witness, Refinery)

GUPP (Gas Town Universal Propulsion Principle) is the propulsion nudge sent
after beacon to trigger autonomous work execution. Previously only polecats
received this nudge.

Now all roles get role-specific propulsion nudges on startup:
- Polecat/Crew: "Run `gt hook` to check your hook and begin work."
- Witness: "Run `gt prime` to check patrol status and begin work."
- Refinery: "Run `gt prime` to check MQ status and begin patrol."
- Deacon: "Run `gt prime` to check patrol status and begin heartbeat cycle."
- Mayor: "Run `gt prime` to check mail and begin coordination."

Changes:
- internal/session/names.go: Add PropulsionNudgeForRole() function
- internal/cmd/witness.go: Add GUPP nudge to ensureWitnessSession
- internal/cmd/start.go: Add GUPP nudge to ensureRefinerySession (also
  converted from respawn loop to direct Claude launch like other roles)
- internal/cmd/deacon.go: Add GUPP nudge to startDeaconSession
- internal/cmd/mayor.go: Add GUPP nudge to startMayorSession
