What to build

Add a --since <commit|tag> flag that limits analysis to files changed since a given git ref. Uses git diff --name-only to get the changed file list, then only analyzes those files. Merges results with a cached previous full analysis.

Useful for CI where full analysis takes too long — only re-analyze what changed.

Acceptance criteria

--since flag accepts a git ref (commit SHA, tag, branch)
Only changed files are parsed by tree-sitter
Results merge with previous full analysis (cache file)
Output is identical to a full analysis when all files have changed
Works with all diagram levels
Tests verify incremental behavior
