feat: terminal search, clickable paths/URLs, ARIA sidebar fixes

Terminal:
- Ctrl+Shift+F opens search overlay (buffer scan, match count, up/down nav)
- Clickable file paths in output (opens in editor, resolves relative paths)
- URL clicks now open in default browser via shell.openExternal
- Right-click pastes directly (selection = copy, no selection = paste)

ARIA Chat:
- Chat fills full sidebar height (flex: 1, removed max-height cap)
- URLs in responses are clickable buttons that open in browser
- Styled with --blue, underline on hover
