Fix canvas autosave wiping pipelines (#18771). Previously saved empty graph on any change/remount. Now only autosaves when canvas has nodes/edges, agent is loaded, and chat drawer closed. Fetch no longer clears loaded canvas on empty DSL. Tests added.
Fixes#18771

### Summary
In agent **Explore**, asking a model and switching to another session
(chat box) while the answer was still streaming caused the streaming
answer to be rendered inside the session the user had just switched to.
**Root cause.** The Explore page mounts `SessionChat` once per canvas;
`useSendAgentMessage` therefore keeps one SSE `answerList` and one
`derivedMessages` list shared by every session. The effect that folds
streamed frames into the message list
(`web/src/pages/agent/chat/use-send-agent-message.ts`) appended
unconditionally, so after a session switch the in-flight frames of
session A were written into the message list of the currently displayed
session B. The global `sendLoading` also made the last assistant message
of session B show a streaming indicator.
**Fix.** Every agent SSE frame already carries the `session_id` it
belongs to (see the frame contract in
`internal/agent/canvas/runner.go`), so ownership is known on the client:
- `useSendAgentMessage` accepts an optional `activeSessionId` (the
session the page is currently displaying) and skips the streamed-answer
append when the stream's `session_id` differs from it. It also exposes
`streamSessionId` so callers can scope streaming UI.
- The Explore hook (`use-send-session-message.ts`) passes the URL
session id as `activeSessionId`.
- `session-chat.tsx` shows the per-message streaming loading state only
when the in-flight stream belongs to the displayed session.
Behavior after the fix: switching sessions mid-answer keeps each
session's message list clean; switching back to the streaming session
resumes rendering the answer there; the answer is still persisted to its
own session by the backend. Canvas debug chat and shared-agent chat are
unchanged (they pass no `activeSessionId`, so the gate is inactive).
**Verification.** Reproduced in the browser (dev services): asked for a
long essay in session A, switched to session B mid-stream — pre-fix,
session B showed session A's growing essay (~27k chars); post-fix,
session B shows only its own history while the stream keeps running
(confirmed by switching back and watching it continue in A). `jest
src/pages/agent` passes (12 suites / 79 tests); `tsc --noEmit` shows no
new errors in the touched files (remaining errors are pre-existing on
main).

Fix Artifacts Tree tab to show error message on navigation API failure instead of misleading "No navigation nodes". Added error handling in frontend, i18n strings, and backend unit tests. 6 tests pass.
Adds Azure DevOps as a new data source, syncing repository files and pull requests. Supports both hosted and self-hosted. Excludes wikis, work items, and binaries. Includes checkpoint/resume, change detection via commit IDs, and handles Azure's quirky 203 auth response. Tests passed against real deployment.
### Summary
Fix IME input breaking in EditTag component. Enter key during Chinese/Japanese/Korean composition would incorrectly commit an incomplete tag. Added e.nativeEvent.isComposing guard so Enter only adds a tag after composition ends. Tests added.
