test(gh-105): 7 new parser tests for maestro-runner 1.0.9 stderr shape

Deferred from PR #159 to keep that PR experiment-scoped. Now landing
as a standalone test PR.

Coverage added:
* Single-quoted id= shape — pinned to verbatim stderr from the #105
  MTTR experiment session
* Double-quoted id= shape
* text= shape (parallel to id=)
* Whitespace tolerance after ':' (parser uses \s*)
* Embedded opposite-quote in selector (matched-quote backreference)
* Full realistic maestro-runner 1.0.9 output (multi-line, includes
  banner + step results + the error line + summary)
* Pattern priority — 1.0.9 id= shape MUST win over the generic
  'Element 'X' not found' fallback when both present

A future maestro-runner upgrade that changes the stderr format will
now trigger an immediate red instead of silently bringing back B152.

1415/1415 unit tests pass (was 1408, +7).
