fix(skill-extractor): walk all brace candidates so stray braces in prose do not swallow valid JSON (#2205)
* fix(skill-extractor): walk all brace candidates so stray braces in prose do not swallow valid JSON

The extractor sliced from the FIRST brace to the LAST brace to recover
JSON embedded in surrounding commentary. When the model emits stray
braces before the JSON object, the slice produces invalid JSON,
json.loads raises, and the exception is swallowed -- the skill is
silently lost.

Fix: walk each brace candidate left-to-right and attempt json.loads on
each slice. The first candidate that parses successfully wins. If none
parse, json.loads on the original text raises and the existing
JSONDecodeError handler logs and returns None as before.

Tested locally -- 8/8 tests passed:
  tests/test_extract_skill_json_nonstring.py (2 passed)
  tests/test_skill_extractor_rows.py (1 passed)
  tests/test_search_content_extraction_parity.py (2 passed)
  tests/test_deep_research_search_error.py (3 passed)

Closes #2199

* test(skill-extractor): add focused repro for stray-brace JSON recovery

* test(skill-extractor): add regression test for leading invalid-brace fragment

Addresses the remaining edge case from review: a response that *starts*
with a brace but the leading fragment isn't valid JSON (e.g.
'{not json}\n{"title": "Valid later", ...}') still needs to recover
the valid skill object that follows.

_extract_json_object (already on dev) handles this correctly — it tries
the whole de-fenced string first, then walks each '{' candidate left-to-
right regardless of whether the response begins with '{', so the leading
invalid fragment no longer short-circuits recovery of the real object.
Updates the comment at the call site to call this out explicitly and adds
a regression test covering exactly the scenario described in review.
