Round 53: Adds 3 hook tests — validates evaluate-session.js
falls back to CLAUDE_TRANSCRIPT_PATH env var when stdin JSON
is invalid, post-edit-console-warn.js truncates output to max
5 matches, and post-edit-format.js passes through data when
the target .tsx file doesn't exist.
The command cross-reference regex /^.*`\/(...)`.*$/gm only captured the
LAST command ref per line due to greedy .* consuming earlier refs.
Replaced with line-by-line processing using non-anchored regex to
capture ALL command references.
New tests:
- 4 validate-commands multi-ref-per-line tests (regression)
- 8 evaluate-session threshold boundary tests (new file)
- 6 session-aliases edge case tests (cleanup, rename, path matching)
