Oxide v0.0.25

Fast codebase index (persistent + incremental) with hybrid semantic rerank (local model2vec, no ONNX); new todo checklist tool; tighter tool descriptions + system prompt; structured tool-call pairing fixes; preview pane + element picker; scoped auto-verify; many UI/stability fixes.

Install: open the dmg, drag Oxide to Applications, then run once: xattr -dr com.apple.quarantine /Applications/Oxide.app
