- Removed `SearchDb` APIs and `searchDb` fields, dropping db-backed state from native and agent sessions.
- Replaced crate export `fff` with `fd`, moving fuzzy-find bindings into `fd.rs`.

- Removed `SearchDb`/`getSearchDb` wiring from extension, tool, and task context constructors across coding-agent.
- Added over-indentation validation warnings in chunk-edit normalization for suspicious `~` body line formatting.
- Removed `bytes`, `fff-grep`, `fff-search`, and `blake3` deps, adding `grep-searcher = "0.1"`.
- Changed chunk edit normalization to prefer write operations, then replace, insert, then delete, with empty write values now treated as clear-content writes.
- Allowed space motions in vim input as `<Space>`, handled them as movement and rendered in error output via token display.
- Adjusted benchmark retry flow to reset files on each retry, reduced per-run call limits, and lowered the default per-turn timeout.
- Normalized chunk edit parsing now detected and warned on entries with multiple write/replace/insert operations, selected one operation by precedence, and ignored the rest.
- Execution now appended those normalization warnings and included them when a chunk edit produced no content changes.
- Updated chunk-edit and vim tool guidance plus vim rendering to document stricter edit usage and expose the current cursor position in output.
When models send multiple operation fields (write + replace + insert),
pick the most substantive: insert > replace > write > delete.
This prevents errors for confused models that populate all fields.
Also properly maps write:null to the delete op instead of put-empty,
and adds the missing case-delete handler in toNativeEditOperation
(fixing a pre-existing TS exhaustiveness error).
