Summary

Unable to copy text out of the seqr REPL, possibly related to mouse capture settings.

Current Behavior

Cannot select and copy text from the REPL output
Standard terminal copy (Cmd+C / Ctrl+Shift+C) doesn't work as expected

Expected Behavior

Should be able to copy:
- REPL history/output
- Stack dump results
- Error messages

Possible Causes

Mouse capture mode in crossterm/ratatui preventing system selection
Terminal raw mode interfering with selection

Investigation Notes

Check crossterm::event::EnableMouseCapture usage
May need to disable mouse capture or provide a "copy mode"
Consider adding explicit copy commands (like tmux's copy mode)

Files to Investigate

crates/repl/src/main.rs - terminal setup
Any mouse event handling code

Implemented F4 toggle for mouse capture:

Problem: EnableMouseCapture captures all mouse events, preventing native terminal text selection for copy/paste.

Solution:

F4 toggles mouse capture on/off
When OFF: native terminal selection works for copying text
When ON: scroll wheel works in IR pane (default)

Also documented:

Most terminals support Shift+Click/Drag to bypass mouse capture for selection (works without F4)

Changes:

Added mouse_capture_enabled field to App
F4 key handler toggles the flag with status message
Main loop sends EnableMouseCapture/DisableMouseCapture when flag changes
Updated :help with COPY/PASTE section

Ready for review.

Simplified solution: Removed mouse capture entirely.

Changes:

Removed EnableMouseCapture/DisableMouseCapture from terminal setup/teardown
Removed mouse event handling from main loop
Removed scroll_ir method (was only used by mouse scroll)
Kept ir_scroll field for potential future keyboard scrolling

Result: Native terminal text selection now works - select and copy with mouse as usual.

CI passes.
