Дмитрий de333852e7 feat(observer): step 3.6 embedding async wiring (phase 4 follow-up)
Mirrors step 3.5 self-assessment pattern (c1ec61fa). When embedding-mode=on
and task is non-trivial (per shouldEmbed), computes Xenova 384-dim embedding
via Promise.race with 2s timeout. Result -> prompt_embedding_base64 base64
string, or null + environment.embedding_unavailable=true on timeout/failure.

Closes Phase 4 follow-up "embedding async wiring" (was deferred from
Phase 3 deferred #2 / parser write-block — parser writes the slot, CLI now
fills it).

Extracted core into exported helper computeEmbeddingForEpisode(ep, ctx, opts)
with injectable embedFn / shouldEmbedFn / encodeBase64Fn / timeoutMs, mirroring
the pure-API style of callSelfAssessmentApi. CLI binds the real router-embedding.mjs
implementations; tests inject fakes. 4 new tests:
  - embedding-mode off -> field null
  - taskType=conversation (exempt) -> embedding skipped
  - embedding success -> base64 string
  - embedding timeout -> environment.embedding_unavailable=true

Regression: 650/650 tests passed (35 test files), 0 failed (excluding 4
pre-existing empty ruflo-*/subagent-prompt-prefix test files).
