fix(test): v0.53.8 CI hardening — strip ANSI + use _repo_root() helper

Five v0.53.8 CI failures (ubuntu/macos × py3.9/3.11/3.12):

1. test_help_lists_hub_flag — Typer's Rich-rendered help wraps long
   option help across ANSI box-drawing lines; "--hub" appears as
   "│ --\nhub" in the CI terminal renderer. Strip ANSI + collapse
   whitespace before asserting.

2-5. test_pyproject_version / test_*_extra_present / test_force_include
   — used `Path("pyproject.toml")` (relative to cwd). CI invokes pytest
   from a different cwd than the repo root on at least one matrix
   entry. Switched to a `_repo_root()` helper that derives from
   `__file__` (matches v0.43.0 Part D demo_bundles approach).

Local re-run: 66/66 v0.53.8 tests pass after the fix.
