refactor: extract CSS modules for terminal and git components (Task 2.2)

- Create TerminalComponent.module.css with terminal-* styles
- Create GitToolbar.module.css with git toolbar styles
- Create CommitDialog.module.css with commit dialog styles
- Create MergeDialog.module.css with merge dialog styles
- Create FileEditor.module.css with file editor styles
- Update all components to import their CSS modules
- Remove extracted rules from styles.css (~441 lines removed)

Quality gates: tsc (pass), eslint (pass), build (pass)

+# Task 2.2 Apply Report: Extract CSS Modules for Terminal and Git Components
+
+**Status:** Success
+
+## Files Created (5)
+
+- `apps/web/src/components/features/terminal/TerminalComponent.module.css` — Terminal component styles (extracted from styles.css)
+- `apps/web/src/components/features/git/GitToolbar.module.css` — Git toolbar styles
+- `apps/web/src/components/features/git/CommitDialog.module.css` — Commit dialog styles
+- `apps/web/src/components/features/git/MergeDialog.module.css` — Merge dialog styles
+- `apps/web/src/components/features/git/FileEditor.module.css` — File editor styles
+
+## Files Modified (6)
+
+- `apps/web/src/components/terminal.tsx` — Import CSS module, replace className strings with styles.* references
+- `apps/web/src/components/git-toolbar.tsx` — Import CSS module, replace className strings
+- `apps/web/src/components/commit-dialog.tsx` — Import CSS module, replace className strings
+- `apps/web/src/components/merge-dialog.tsx` — Import CSS module, replace className strings
+- `apps/web/src/components/file-editor.tsx` — Import CSS module, replace className strings
+- `apps/web/src/styles.css` — Removed extracted terminal and git component CSS rules (~441 lines removed)
+
+## Quality Gate Results
+
+- `npm run typecheck` (frontend): **PASS** — zero errors
+- `npm run lint` (frontend): **PASS** — zero warnings
+- `npm run build` (frontend): **PASS** — build succeeds in 9.70s
+- No remaining `.terminal-*`, `.file-editor`, or `.commit-dialog` rules in styles.css
+
+## Notes
+
+- CSS classes converted from kebab-case to camelCase for CSS Modules usage
+- Generic/shared classes (form-group, btn-primary, btn-secondary, error-message) remain in styles.css
+- Dynamic diff line classes handled with conditional className assignment
+- `styles.css` reduced from 2696 lines to 2255 lines
