## Description

GitHub Linguist's *vendor.yml* classifies the entire `.github/`
directory as vendored, which excluded all Python skill files from the
repository's Languages API. OSSF Scorecard's Fuzzing check only
evaluates languages that appear in that API, so the Atheris fuzz harness
merged in PR #1102 remained invisible and **Fuzzing scored 0/10**
despite correct test infrastructure.

> The root cause was a mismatch between where skills live
(`.github/skills/`) and Linguist's vendored-path regex. The fix adds a
targeted `.gitattributes` override rather than relocating files.

- Added **`linguist-vendored=false`** for `.github/skills/**/*.py` in
*.gitattributes*, overriding the vendored classification so Python
appears in language statistics
- Included an explanatory comment documenting the Linguist vendor.yml
interaction with OSSF Scorecard for future maintainers
- Removed two duplicate `**/.hypothesis/` entries from *.gitignore* (the
file contained three identical lines; one remains)

**Other:**

* [ ] Script/automation (`.ps1`, `.sh`, `.py`)
* [ ] Other (please describe):

## Testing

- Verified `git check-attr linguist-vendored --
.github/skills/experimental/powerpoint/tests/fuzz_harness.py` returns
`false`, confirming the override is active.
- Confirmed the `.github/skills/**/*.py` glob covers all 35 Python files
(427,782 bytes), approximately 3.5x the Linguist prominence threshold.
- Ran `npm run validate:skills` — all 9 skills passed with 0 errors.

## Checklist

### Required Checks

* [ ] Documentation is updated (if applicable)
* [x] Files follow existing naming conventions
* [x] Changes are backwards compatible (if applicable)
* [ ] Tests added for new functionality (if applicable)

### AI Artifact Contributions

* [ ] Used `/prompt-analyze` to review contribution
* [ ] Addressed all feedback from `prompt-builder` review
* [ ] Verified contribution follows common standards and type-specific
requirements

### Required Automated Checks

The following validation commands must pass before merging:

* [x] Markdown linting: `npm run lint:md`
* [x] Spell checking: `npm run spell-check`
* [x] Frontmatter validation: `npm run lint:frontmatter`
* [x] Skill structure validation: `npm run validate:skills`
* [x] Link validation: `npm run lint:md-links`
* [x] PowerShell analysis: `npm run lint:ps`
* [x] Plugin freshness: `npm run plugin:generate`

## Security Considerations

* [x] This PR does not contain any sensitive or NDA information
* [x] Any new dependencies have been reviewed for security issues
* [x] Security-related scripts follow the principle of least privilege

## Additional Notes

- The 35 Python files under `.github/skills/` total approximately
427,782 bytes, which is well above the Linguist prominence threshold
(~122,000 bytes). Even if small files are added or removed, Python
visibility in the Languages API remains stable.
- No new dependencies were introduced. The change is purely metadata
(`.gitattributes` and `.gitignore`).
