Respect exclusions before reporting DeepSearch path matches

[FanWu-ai]

DeepSearch reports matching dictionary keys and attribute names before the recursive search checks exclusions. For example, DeepSearch({'needle': 'x'}, 'needle', exclude_paths=["root['needle']"]) currently reports the excluded path in matched_paths.

Check the child object and its path with the existing exclusion predicate before reporting a path match. Add ten regression cases covering exact, wildcard and regex path exclusions, attribute names, excluded child types, retained siblings, and both verbosity levels.

This complements #629: that change fixes the recursive current-object type check, while this fixes the earlier path-reporting step. All eight initial path-exclusion regressions still fail with #629's production change alone.

Validation on Linux, CPython 3.12.14:

• Full suite including slow tests: pytest --cov=deepdiff --runslow --benchmark-disable -q: 1,319 passed, 8 skipped; 95% aggregate coverage.
• Search suite: 72 passed; 100% coverage of deepdiff/search.py.
• pyright deepdiff/search.py: 0 errors, 0 warnings.
• CI-blocking Flake8 rules E9,F63,F7,F82 and git diff --check: passed.
• Full Flake8 on the touched files reports seven pre-existing diagnostics, compared against the unchanged baseline; no new diagnostics.

Other Python versions, operating systems, and hosted CI have not been validated locally.
