Problem

Commands differ across versions, but the docs site always shows the latest. Users on 0.3.0 see 0.3.3 docs and try commands that don't exist in their version.

Proposal

Version-scoped documentation on GitHub Pages:

• /git-parsec/ → latest version (preserve current URLs)
• /git-parsec/v0.3.3/ → specific version
• Version selector dropdown UI
• Auto-snapshot in release workflow

Acceptance criteria

• At least 2-3 recent versions accessible
• Version switcher UI (dropdown or banner)
• Auto-snapshot on release
• Latest version preserves existing URLs (SEO)

Milestone

v0.4
