fix: exclude .patchloom/ from git tracking and VSIX package (#121)

The .patchloom/backups/ directory is created by the CLI during testing
and normal use. Without these exclusions:

- git status shows untracked .patchloom/ for anyone running tests locally
- vsce package bundles 70 backup files (8 KB) into the published VSIX

Add .patchloom/ to both .gitignore and .vscodeignore.
