What

User-facing text about relaunching a session now says environment instead of pool.

Details
  • The requeue confirmation reads "This re-launches the session on another runner in the environment."
  • The secret-claim error says it "cannot derive the environment ID for spawn-hint polling".
Evidence

This re-launches the session on another runner in the environment.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
