3fa15c0e2f feat(agent): Go port — canvas engine, 22 components, DSL v2, 13 endpoints (#15952)
Ports the agent canvas subsystem from Python to Go.

## What's included

### Canvas Engine (Phase 0/1)
- State engine, scheduler, variable resolver, Redis checkpoint store,
cancel protocol
- **209 tests** across canvas / component / io packages

### 22 Components (P0–P4)
| Tier | Components |
|---|---|
| P0 T1+T2+T3 | LLM, Agent, ExitLoop, Switch, Categorize, Begin,
Message, Invoke |
| P1 T3 | VariableAggregator, VariableAssigner, StringTransform,
ListOperations, DataOperations |
| P2 T3 | Iteration, IterationItem, Loop, LoopItem |
| P3 T3 | UserFillUp, Fillup |
| P4 T5 | Browser, ExcelProcessor, DocsGenerator |

### DSL v2 Schema (Phase 2.5)
- Typed v2 in-memory model with v1-to-v2 auto-detect converter
- v1 legacy field stripping per plan §2.11.7

### HTTP Endpoints & Bug Fixes (Plans PR1–PR3)
- **DELETE SQL bug fix**: gorm v2 `Where("id = ?", id).Delete(...)`
pattern
- **CreateAgent validation**: title/DSL required, duplicate check, 103
envelope
- **13 new endpoints**: templates, prompts, tags, sessions CRUD,
chat/completions (SSE + non-stream stubs), rerun, test_db_connection,
logs, webhook/logs
- **756 Go unit tests** (745 → 756, +18)
- **17 → 0 Python integration test failures** (test_agents.py +
test_session_management/)

### Tools
21 eino tools: HTTPHelper, search tools, financial/data tools, mandatory
stubs

02d163a177 feat: implement GET /api/v1/agents/<agent_id>/versions API (#15629)
## Summary

Implement the `GET /api/v1/agents/<agent_id>/versions` endpoint in Go,
listing all version snapshots for an agent canvas in descending update
time order.

### Changes

- **New**: `internal/dao/user_canvas_version.go` —
`UserCanvasVersionDAO` with `ListByCanvasID` (ordered by update_time
DESC) and `GetByID`
- **Modified**: `internal/service/agent.go` — Added `CheckCanvasAccess`,
`ListVersions`, `GetVersion` methods
- **Modified**: `internal/handler/agent.go` — Added `ListAgentVersions`
handler with auth check
- **Modified**: `internal/router/router.go` — Registered `GET
/:agent_id/versions` route
- **New**: `internal/service/agent_test.go` — 5 service-level tests
(SQLite in-memory DB, zero mock)
- **Modified**: `internal/handler/agent_test.go` — 3 handler-level tests
(real DB, pre-authenticated context)

### Testing

All 8 tests pass with zero mocking (in-memory SQLite replaces MySQL):

```
=== RUN   TestListVersions_Success         --- PASS
=== RUN   TestListVersions_Empty           --- PASS
=== RUN   TestCheckCanvasAccess_Owner      --- PASS
=== RUN   TestCheckCanvasAccess_NotOwner   --- PASS
=== RUN   TestCheckCanvasAccess_NotFound   --- PASS
=== RUN   TestListAgentVersionsHandler_Success      --- PASS
=== RUN   TestListAgentVersionsHandler_NoPermission --- PASS
=== RUN   TestListAgentVersionsHandler_CanvasNotFound --- PASS
```
