🟡 Changes recommended

The new transcript helper can throw on missing/unreadable transcript paths, and the end-to-end integration test currently hard-fails when the external claude CLI is unavailable (making node --test brittle).

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Adds Claude plugin lifecycle hook scripts and supporting utilities to prompt for Stripe agent feedback (sampled per batch/turn and on failures), report Stripe Skill usage, and provide Stripe CLI setup/update guidance at session start—plus unit/integration tests and hook wiring.

Changes:

Add lifecycle hook executables for SessionStart, PostToolBatch, PostToolUse, PostToolUseFailure, and UserPromptSubmit.
Introduce transcript scanning utilities to detect Stripe mentions in the latest turn and drive per-turn feedback emission.
Add CLI helpers and comprehensive test coverage (unit + integration), and bump plugin versions.

i dont love that this is hardcoded into a plugin we don't control, but since this is experimental this is easier

should we use stripe whoami instead

does it make sense to keep these in the CLI itself?

do these tests get shipped to the end plugin binary? or they are they filtered out?
