The xterm.js WebGL addon has known rendering bugs with reverse-video
(inverse color) ANSI sequences — exactly what tmux uses for its status
bar, pane borders, and selected text. On desktop the WebGL addon loaded
successfully, causing characters to render as black-on-black and appear
to 'disappear'. On mobile WebGL typically fails to initialize, so the
terminal silently fell back to the DOM renderer which handles these
color attributes correctly.
- Remove WebGL addon loading and its cleanup logic
- Remove unused xterm-addon-webgl import and dependency
- DOM renderer is the default and correctly handles all ANSI color
attributes including reverse video

Fixed import paths for 43 components moved into features/ directories.
Key fixes:
- api/, types/, hooks/, state/, utils/ imports need ../../../ from features/*/
- components/ imports need ../../ from features/*/
- Cross-feature imports use relative paths (e.g., ../tool/tools-bottom-sheet)
- app-shell.tsx updated to import from features/ subdirectories
Frontend typecheck now passes except for one pre-existing error:
xterm-addon-webgl missing type declarations.
Quality gates: ruff passed on backend, py_compile passed on all backend files.
