refactor: rename files to PascalCase components and kebab-case APIs (Task 4.4)

- Rename all component files to PascalCase matching exported names
- Move components into feature directories (git/, session/, project/, terminal/, workspace/, ui/, layout/)
- Rename all page files to PascalCase with Page suffix
- Rename all API files to kebab-case
- Update all imports across codebase with corrected relative depths
- Preserve git history via git mv

Quality gates: tsc (pass), eslint (pass), 66/74 tests pass (8 pre-existing failures)
