Two version-compat fixes for the `devx` debugger
test-suite, both about matching upstream output that
got more verbose w/ recent lib releases.
ANSI stripping (`tests/devx/conftest.py`),
- Add `ansi_strip(text)` helper + `_ansi_re` pattern
(regex per https://stackoverflow.com/a/14693789).
- Apply inside `in_prompt_msg()` + `assert_before()` so
substring matches against REPL/traceback output stay
robust to color leakage.
- Motivated by py3.13's colored tracebacks +
`pdbp`/pygments highlighting leaking ANSI even when
`PYTHON_COLORS=0` is set in the `spawn` fixture (not
every renderer in the spawned subproc honors it).
- Replaces the longstanding inline TODO that linked
the SO answer w/o impl'ing.
trio 0.30+ `Cancelled._create(` match (`test_debugger`),
- In `test_shield_pause` swap the two
`"raise Cancelled._create()"` assertion patterns →
`"raise Cancelled._create("` (open-paren form, no
closing).
- trio >=0.30 raises a multi-line
`raise Cancelled._create(source=.., reason=..,
source_task=..)` w/ cancel-reason metadata, so the
legacy bare-`()` form no longer matches. Inline
comment documents the trio-version pivot.
