feat: migrate DELETE /api/v1/datasets/:dataset_id/documents to Go (#15577)

## Summary Migrate the batch document deletion endpoint from Python to Go. Two modes supported: explicit `ids` list and `delete_all`. ## Changes | File | Change | |------|--------| | `internal/dao/file2document.go` | Add `GetByDocumentID`, `DeleteByDocumentID` | | `internal/dao/file2document_test.go` | 5 new tests | | `internal/dao/kb_test.go` | 2 new tests (`DecreaseDocumentNum`) | | `internal/service/document.go` | Add `deleteDocumentFull` + `DeleteDocuments`, refactor `DeleteDocument` | | `internal/service/document_test.go` | 10 new tests | | `internal/handler/document.go` | Add `documentServiceIface` + `DeleteDocuments` handler | | `internal/handler/document_test.go` | 7 new tests | | `internal/router/router.go` | Register `DELETE /:dataset_id/documents` | | `cmd/server_main.go` | Support `RAGFLOW_DICT_PATH` env var | | `internal/binding/rag_analyzer.go` | Use `-lpcre2-8` dynamic linking | | `internal/dao/database.go` | Skip Error 1091/1138 during migration | | `internal/service/llm.go` | Fix vet warning | ## Per-document cleanup - Delete tasks from DB - Hard-delete document + decrement KB counters - Delete chunks from document engine (nil-guarded) - Delete metadata from document engine (nil-guarded) - Remove file2document mapping + file record + storage blob ## Test Results **24 unit tests all passing** (7 DAO + 10 service + 7 handler) using SQLite :memory: + gin.TestMode. See [test report](docs/test_report_delete_documents.md) for manual integration test results. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
