## Why Memory baseline snapshots need bounded file reads, and recovery must keep existing memory files visible to consolidation rather than treating them as already processed. ## What changed - Limit baseline files to 10 MiB, skip oversized working files, and check stored blob sizes before reading them. - Version baselines and replace missing, outdated, or unusable metadata with an empty baseline, preserving working files as additions. Also invalidate the baseline when a tracked file grows beyond the limit. - Serialize baseline initialization, resets, and diffs with a cross-process lock. Isolate repository access and pin index writes to the baseline worktree. ## Testing Add coverage for oversized files, legacy baseline migration, interrupted resets, cross-process locking, and consolidation with unchanged inputs after baseline recovery.

Helpers for interacting with git, including patch application. The crate also
exposes a lightweight baseline API for internal directories that use git only
as a resettable diff mechanism: ensure_git_baseline_repository preserves a
usable root/.git baseline or creates one when it is missing or unusable,
reset_git_repository replaces root/.git with a fresh one-commit baseline,
and diff_since_latest_init returns structured file changes plus a unified
diff from that baseline to the current directory contents.
