chore: keep npm package documentation minimal

[254808127]

Summary

• remove internal docs/ materials from the repository tree
• ignore docs/ in Git and npm packaging
• keep only README.md as package documentation
• remove Linux-only content from the current user-facing README
• update the preview status after Windows x64 and macOS ARM64 E2E validation

Validation

• npm run check
• npm run package:verify
• npm payload contains 19 files and only README.md as Markdown
• git diff --check

Linux support remains deferred and is not added by this change.

One bug found.

README.md line ~51 contains a truncated commit hash:

`native-source.json` pins `browser-cli` v1.1.13 at commit `3af544780365309fe97d51b631070e7ca73762`.

The hash is 38 hex characters; a valid SHA-1 is 40. It is missing ae after 309fe. The authoritative value in native-source.json is:

3af544780365309feae97d51b631070e7ca73762

No bugs or security issues found.

The previously flagged truncated commit hash (3af544780365309fe97d51b631070e7ca73762, 38 chars) has been corrected. README.md line 31 now reads 3af544780365309feae97d51b631070e7ca73762 (40 chars), matching native-source.json exactly.

All other changes are consistent:

• .gitignore and .npmignore correctly exclude docs/
• package.json files array removal of "docs/*.md" matches the deleted directory
• README platform table and cache table removals match the stated Linux-deferred scope
