BrainPalace 26.6.25

Changed

• Git history indexing now indexes the full history by default. The git_indexing.depth default changed from 1000 to 0 (no cap) — a silent 1000-commit cap surprised users (status stuck at "1,000 commits" on larger repos and dropped the oldest history). Set a positive depth to bound the first full pass on very large repos (each commit is an embedded chunk, so an unbounded first index of a huge repo costs more time/embeddings).
• brainpalace init now asks how many commits back to index when you opt into git history (default 0 = unlimited), writing git_indexing.depth.
