The previous check only looked for ".." substring, which missed:
- Absolute paths (/etc/passwd)
- URL-encoded traversal patterns
- Paths that clean to traversal (./../../etc)
Now uses filepath.Clean() and filepath.IsAbs() for robust validation:
- Rejects absolute paths
- Cleans paths before checking for traversal
- Uses cleaned path for database lookup

When indexing a revision that already exists, the indexer now returns
early with information about the existing revision instead of re-indexing.
Use the --force flag to re-index an existing revision.

File indexing only adds ~3 seconds to the indexing process, so enable
it by default to make the get_file tool work out of the box.
- MCP index_revision tool now indexes files automatically
- CLI flag changed from --files to --no-files (opt-out)
- Update README examples
