0.2.0

Changed

• Git-free snapshot undo. "Undo last run" no longer relies on the vault being a git
  repository. Before a run writes a note, the plugin snapshots that note's pre-run state
  (copy-on-write, write-ahead) into a hidden store under
  .obsidian/plugins/vault-crews/undo/<runId>/, via the Obsidian vault/adapter API only.
  Undo restores changed notes from the snapshot and moves run-created notes to the
  Obsidian trash (never a hard delete). This works in every vault, not just git repos.
• Honest conflict warning. If a note was edited after the run but before undo (detected
  via content hash), the confirmation dialog warns before rolling it back — never a silent
  overwrite.
• New setting "Undo history depth" (default 15) controls how many recent runs keep an
  undo snapshot; older snapshots are pruned automatically.

Removed

• All child_process and node:fs usage. The git-backed undo (system git commit /
  git revert) is gone, so the plugin no longer performs shell execution or direct
  filesystem access — removing both Community-store review "Behavior" warnings. Vaults that
  want a permanent versioned history can still run git themselves; the run logs
  (run.md) remain the durable human-readable record.
