Feature Request: Session favorites/bookmarks with keyboard shortcut (Ctrl+F)

[Her-xanadu]

Summary

Add the ability to favorite/bookmark sessions for easier organization and quick access, especially for long-term users who accumulate hundreds of sessions over time.

Motivation

When using OpenCode for months or years, the session list becomes overwhelming with purely time-based sorting. Users need a way to:

• Mark important sessions for quick access
• Organize sessions by category/project
• Archive completed work sessions

Proposed Solution

1. Quick Favorite (Minimal)

• Add Ctrl+F keyboard shortcut in TUI to toggle favorite on current session
• Show ⭐ icon next to favorited sessions in session list
• Add filter option to show only favorites

2. Session Tags/Categories (Extended)

• Allow adding custom tags to sessions (e.g., work, learning, archived)
• Filter session list by tag
• Store metadata in ~/.config/opencode/session-meta/ (separate from core session data)

Suggested Session JSON Extension

{
  "id": "ses_xxx",
  "title": "...",
  "favorite": true,
  "tags": ["work", "important"],
  ...
}

Alternatives Considered

• External tools like agent-archives - has compatibility issues (Python path problems on macOS)
• Custom slash commands with shell scripts - works but not as smooth as native TUI integration

Additional Context

I've created a workaround using a shell script (oc-session) and custom /tag command, but native TUI support would be much better UX.

Would be happy to contribute a PR if the team is open to this feature direction.
