v0.3.10

Correctness release for contextual wrapper preservation and built-in idempotency.

Fixed:

• Preserves closing quotes and common wrappers around Bearer auth, URL query secrets, cookie values, and bare key-value secrets.
• Adds placeholder guards across contextual built-in rules so a second ShareClean pass produces zero repeat findings.
• Keeps support for both the default [REDACTED] label and custom labels such as <SECRET>.

Validated:

• python -m unittest discover -s tests -v
• python -m compileall -q src tests
• node --check docs/app.js
• python -m build --sdist --wheel
• python -m twine check dist/*
