Extension 0.6.0: next-edit, token healing, TS errors context, cursor-move, prewarm

- shared/nextedit.ts: next-edit prompt format (region rewrite or NO_EDIT, Qwen spare special tokens)
- shared/diagnostics.ts: TS errors near the cursor as context; symbols format 2 adds namespace imports
- shared/prompt.ts: token healing (cut the half-typed word, force it via grammar), errors header section
- daemon: model profiles carry contextFormat/errors/members/nextEdit; /v1/next-edit with edit-burst
  tracking; /v1/prewarm; /v1/debug/last; token healing on by default
- extension: next-edit decorations (Tab apply / Esc dismiss), suggest on cursor move, prewarm on focus,
  Show Last Prompt, update check against releases, diagnostics in the edit recorder
- models/README: training-data attribution; release script profiles for stage-d/stage-e
- .gitea/workflows/ci.yml: build + test, publish release on vscode-v* tags (needs a runner + RELEASE_TOKEN)
