Port dataset-level wiki incremental compile and refactor splitByTokens
token budgeting. Includes replace-only wiki merge, KNN dedup routing,
and template/config wiring.
## What changed
- add an OceanBase/SeekDB Go document engine using `database/sql` and
the existing MySQL driver
- preserve the Python connector's configuration, physical table names,
schema, index names, and ARRAY/JSON/VECTOR encodings
- implement chunk, memory, document metadata, skill, SQL, full-text,
vector, and fusion search paths
- support `DBMS_HYBRID_SEARCH.SEARCH` behind the existing feature flag,
with SQL fallback only when the package is unavailable
- wire the engine into retrieval, memory, metadata, vector hydration,
and SQL chat flows
- add Python/Go compatibility contracts, SQL mock tests, and an
integration-tagged round-trip test

Re-materialize wiki page graph from merged wiki_page rows after each
batch merge. Adds ProjectWikiGraph/DropWikiGraph, full page_type/slug
identity, delete-then-insert, tests.
## Summary
- Add embedding batch-size metadata to model responses and tenant
overrides.
- Validate embedding dimensions and batch limits across provider
verification and embedding requests.
- Expand validation tests for defaults, limits, and missing metadata.

Ports dataset knowledge compilation (wiki/graph/tree/mindmap) to the Go
scheduler with a status contract, aligns wiki storage/retrieval with
Python, sizes prompts by content_length, and resolves embedding batch
size from provider capability.

- Prefer canonical `dataset_ids` over legacy `kb_ids` in Canvas
retrieval components.
- Cover selected and explicitly cleared dataset IDs with regression
tests.
- Add cross-language retrieval with dataset-specific embedding and
rerank models.
- Support vector and keyword similarity controls, metadata filtering,
TOC enhancement, and child-chunk expansion.
- Route Canvas retrieval across datasets and memories with compatible
embedding validation.
Port Python rag/advanced_rag agentic search to Go: ES-backed dataset-nav
service, agentic-search harness, and agent tools.
Includes agentic-search port plan and self-review docs.
## Summary
- Align Go agent logs access with the Python behavior by checking tenant
access to the target agent instead of requiring the token to be bound
to that agent.
- Marshal canvas lifecycle event payloads safely so non-serializable
inputs do not break Thinking expansion in the UI.
## Testing
- `CGO_ENABLED=0 go test -count=1 -v -run
"Handler|Attachment|Logs|Chatbot|Agentbot|BuildWorkflow|NodeLifecycle|VarRef|Resolve|Extract"./internal/handler/
./internal/agent/canvas/...` PASS
### Summary
Aligns Go and Python error codes/messages so both backends honor the
same RESTful API contract, removing implementation-specific error leaks
(MySQL errors, `ValueError`, `AttributeError`, Gin validator format) in
favor of clean business error codes.
**Chat list** — invalid `orderby` now returns code 101 (was: raw Python
`AttributeError` code 100); invalid `page`/`page_size` values fall back
to defaults (was: raw `ValueError`/`ProgrammingError` code 100).
**Dataset create/update/delete** — adds UUID validation (101),
extra-field rejection (101), duplicate-id detection (101), content-type
/ JSON-syntax / object-shape checks (101), and "lacks permission" for
nonexistent datasets (IDOR). Create auto-deduplicates dataset names.
Pagerank updates tolerate a missing ES index. List response includes
`parser_config` and `pagerank`.
**Session list/update** — adds filtering, sorting, and pagination
support. Empty payloads are valid no-ops. Authorization errors map to
code 109.
**Chunk list** — doc object uses Python key names (`chunk_count`,
`dataset_id`, `chunk_method`, run text status). Add validates list
element types.
**Document update** — adds `chunk_method` alias, pydantic-style Field
error messages, metadata index auto-create with refresh, and "These
documents do not belong to dataset" messages. List validates
`metadata_condition` and reports ownership errors for unmatched name/id
filters.
**Search completion** — `kb_ids` ownership failure returns code 102
instead of 109.
Released 31 contract tests from `GO_ONLY_SKIPS` (all verified passing on
both Go and Python backends with real LLM keys).
