release: v0.3.15 — upgrade Linux binary to .159.7, StorageBuckets normalization

Binary:
- Upgrade Linux x64 build to Chromium 145.0.7632.159.7 (33 C++ patches)
- StorageBuckets API quota normalization — closes last storage-based incognito detection vector

Wrapper:
- Fix non-ASCII character support in humanized typing (Cyrillic, CJK, emoji)
- Document storage quota tradeoff for persistent contexts
- Add Ko-fi funding link
