fix(yuanbao): track new hunyuan_t1 SSE protocol and align inline citations with DeepSeek

- findInteractiveByText now also accepts elements carrying business
  attributes [dt-button-id]/[data-button-id]. The new yuanbao toolbar
  renders the deep-think toggle as <div dt-button-id="deep_think"> rather
  than a <button>, so the previous text-only locator missed it and probes
  silently ran in the fast model — without inline citations.
- Lower <div data-idx-list="1,2,10"> placeholders to bare "[1][2][10]"
  (previously "[citation:1] [citation:2] [citation:10]") and accept both
  forms in YUANBAO_CITATION_MARKER_PATTERN. Final answer text runs through
  normalizeCitationMarkers so any residual SSE [citation:N] is rewritten
  to [N], matching DeepSeek's chip rendering on the SaaS side.
- searchGuid frames in the new protocol carry every reference inside
  docs[] (each with a 1-based index that mirrors the answer markers) and
  citations is now always null. Promote docs into the citations bucket so
  citations[index-1] aligns with the inline marker, eliminating the
  spurious yuanbao_incomplete_citations failures.
- Update the SaaS detail view: createYuanbaoCitationPattern accepts both
  "[N]" and "[citation:N]" so yuanbao answers render the same clickable
  superscript chips as DeepSeek.

Tests cover the new searchGuid.docs alignment, fast-cache answers (no
markers, no sources -> still succeed), legacy [citation:N] -> [N]
rewriting, and mixed-format marker extraction.
