Summary

Rename shuttle chrome bookmarks commands to the local-centric convention agreed across shuttle:

• import — external → local (chrome.bookmarks_file)
• export — local → external (apply backup to Chrome)

Parent: #24 · relates to Notion naming in #2.

Scope

• Swap Typer command names in shuttle/commands/chrome.py
• Keep old names as hidden aliases (export → import behavior, import → export behavior) for one release
• Update scripts/chrome/export.sh / import.sh help text (scripts keep internal names)
• Update README, docs/bookmarks.md, integration endpoint registry, tests

Verification

• shuttle chrome bookmarks import pulls HTML from Chrome into configured path
• shuttle chrome bookmarks export restores from local file into Chrome
• Legacy shuttle bookmarks export still works (hidden alias)

Execution

@gh-issue-execute → rename + aliases → @gh-pr
