- Switched search/ast_grep/ast_edit/find inputs from scalar path fields to required `paths` arrays.
- Reworked path resolution to normalize and expand each `paths` entry via explicit helpers in `src/tools/path-utils.ts`.
- Updated search and find tool-call rendering to display explicit `paths` values in mode overlays and export views.
- Updated tool prompt docs and examples to document `paths` array inputs for search, grep, find, and AST tools.
- Raised the default search match limit from 20 to 500 and updated limit-reached messaging.
- Fixed path resolution to emit per-target fanout when common base collapses to filesystem root, preventing full-filesystem scans.
- Fixed match/file counts and pagination to aggregate correctly across all targets.
- Fixed returned paths to be normalized relative to the original search scope.
