feat(collect): add local directory collection

Add `borg collect local` command to collect files from the local
filesystem into a DataNode.

Features:
- Walks directory tree (defaults to CWD)
- Respects .gitignore patterns by default
- Excludes hidden files by default (--hidden to include)
- Custom exclude patterns via --exclude flag
- Output formats: datanode, tim, trix, stim
- Compression: none, gz, xz

Examples:
  borg collect local
  borg collect local ./src --output src.tar.xz --compression xz
  borg collect local . --format stim --password secret
