feat: complete v0.4 remaining items — camelCase params, errorCategory, search error detection + audit fixes

- Rename annotation input params to camelCase (noteText/fileName/mimeType/documentBody)
- formatPrerequisiteError now includes errorCategory inferred from prerequisite.type
- delete_attribute and update_entity error catches include errorCategory: SCHEMA_MISMATCH
- dataverse_search: comprehensive regex for disabled-search detection (7 patterns)
- Fix search error code: 0x87300005 (incorrect) -> 0x80048D0B (documented Dataverse code)
- Upgrade search endpoint from /api/search/v1.0/query to v2.0 (current API)
- Roadmap: mark all 3 v0.4 Schema Consistency items as Done
- Bump version to 0.4.2

+### Changed
+
+- **Uniform camelCase parameter names in `dataverse_create_annotation`**: `notetext` → `noteText`, `filename` → `fileName`, `mimetype` → `mimeType`, `documentbody` → `documentBody`. Dataverse wire field names in the POST body are unchanged.
+- **`errorCategory` in all structured error responses**: `formatPrerequisiteError` now automatically infers and includes `errorCategory` (`ENV_LIMITATION` for `feature_disabled`, `PERMISSIONS` for `permission_required`, `SCHEMA_MISMATCH` for `schema_missing`). `dataverse_delete_attribute` (error codes `0x80048405`, `HAS_DEPENDENCIES`) and `dataverse_update_entity` (`0x80060888`) also include `errorCategory: "SCHEMA_MISMATCH"` in their error payloads.
+- **`dataverse_search` expanded error detection**: The Relevance Search disabled check now uses a comprehensive regex covering HTTP 403/404/400, `0x80048D0B` (official Dataverse error code for disabled search), `search disabled`, `search not configured`, and `search unavailable` messages — up from 2 patterns to 7.
+- **Search API upgraded to v2.0**: The Dataverse search endpoint is now `/api/search/v2.0/query` (was `v1.0`, which is legacy/deprecated).
