fix: update docs for ironmark/Rust, fix theme count, fix download temp file race

- Add Rust to prerequisites in all docs (README, AGENTS, getting-started, installation)
- Add CIronmark and Vendor/ironmark to project structure docs
- Fix clone URL placeholder (your-username -> ph1p)
- Update theme count from 14 to 32 with all missing themes
- Update test counts (391/492 -> 717)
- Remove non-existent Renderer/ directory from contributing docs
- Fix update download: move temp file synchronously in delegate callback
  before URLSession deletes it, instead of deferring to main queue
