🔍 Implement text search/find functionality (Ctrl+F)

[kshivang]

Feature Description

Add text search/find functionality to compose-ui terminal, matching the capabilities of the legacy Swing UI.

Current Status

❌ NOT IMPLEMENTED - No search functionality exists in ProperTerminal.kt

Legacy UI Capabilities

The legacy ui/ module has:

• JediTermSearchComponent - Full search UI component
• SubstringFinder - Text search logic with highlighting
• TerminalSearchUtil - Search utilities
• Find next/previous navigation
• Regex search support
• Result highlighting with custom colors

Proposed Implementation

1. Search UI Component

• Floating search bar overlay (similar to browser Ctrl+F)
• Text input field for search query
• "Find Next" / "Find Previous" buttons
• "Match Case" toggle
• "Regex" toggle (optional)
• Close button (X)
• Result counter (e.g., "3 of 12")

2. Core Search Logic

Port from legacy code:

• SubstringFinder.kt logic from jediterm-core-mpp
• Search through terminal text buffer
• Handle wrapping (search from top when reaching bottom)
• Support both history buffer and screen buffer

3. Visual Highlighting

• Highlight all matches in yellow background
• Current match in orange/different color
• Scroll to current match automatically
• Clear highlights when search closed

4. Keyboard Shortcuts

• Ctrl+F / Cmd+F - Open search
• Enter / F3 - Find next
• Shift+Enter / Shift+F3 - Find previous
• Escape - Close search

Priority

🔴 HIGH - This is the #1 most-used terminal feature after copy/paste
