Taro Kawakami a35b2d125d fix(hooks): isolate session-end.js filename using transcript_path UUID ...

When session-end.js runs and CLAUDE_SESSION_ID is unset, getSessionIdShort()
falls back to the project/worktree name. If any other Stop-hook in the chain
spawns a claude subprocess (e.g. an AI-summary generator using 'claude -p'),
the subprocess also fires the full Stop chain and writes to the same project-
name-based filename, clobbering the parent's valid session summary with a
summary of the summarization prompt itself.

Fix: when stdin JSON (or CLAUDE_TRANSCRIPT_PATH) provides a transcript_path,
extract the first 8 hex chars of the session UUID from the filename and use
that as shortId. Falls back to the original getSessionIdShort() when no
transcript_path is available, so existing behavior is preserved for all
callers that do not set it.

Adds a regression test in tests/hooks/hooks.test.js.
