refactor: rebrand as @photostructure/sqlite-vec

Changed npm package name from @mceachen/sqlite-vec to @photostructure/sqlite-vec
to reflect that PhotoStructure Inc. is funding and maintaining this fork.

**Changes:**
- package.json: Update name, version (0.4.1), repository URLs
- README.md: Update branding to "PhotoStructure's Production Fork"
- Explain why fork exists (PhotoStructure's production dependency)
- Update installation instructions for new package name
- Credit original authors (Alex Garcia, Vlad Lasky) prominently

**Rationale:**
- Honesty: PhotoStructure is paying for maintenance, should own branding
- Sustainability: Company ownership reduces bus factor
- Professional: Standard practice for companies maintaining infrastructure
- Transparent: Users know who's backing the dependency

This remains open source (MIT/Apache-2.0). Contributions welcome.

 > **Fork improvements:**
-> - Security hardening (safe integer parsing, vendor checksum validation, pinned CI actions, OIDC releases)
-> - Fixed multiple memory leaks via AddressSanitizer/Valgrind testing (see [CHANGELOG](CHANGELOG-mceachen.md))
-> - Node.js: added Alpine/musl and Windows ARM64 prebuilds, all platforms bundled (no post-install scripts)
-> - Updated to latest SQLite release
+> - **Testing:** AddressSanitizer/Valgrind/UBSan integration, 30+ error path tests, memory leak fixes
+> - **Security:** Safe integer parsing, vendor checksum validation, pinned CI actions, OIDC releases
+> - **Node.js:** Alpine/musl + Windows ARM64 prebuilds, bundled binaries (no post-install scripts)
