fix(kimi): keep monitor robust against K2.6 redesign noise

K2.6 introduced new UI surfaces that polluted the answer extraction and
the busy-signal probe, breaking monitor runs even though Kimi rendered a
correct answer:

- collectCandidates now drops elements that contain a chat composer child
  (<textarea>, non-hidden <input>, [contenteditable]). This filters
  wrapper containers like .chat-detail-content that the wide
  [class*="content"] fallback would otherwise pick, pulling editor
  placeholder text ("可快捷使用技能", "Kimi K2.6 已就位") into the answer.
- isAuxiliaryPanelElement skips elements with role="dialog" /
  "alertdialog", aria-modal="true", or the <dialog> tag, so the K2.6
  launch-announcement popover ("Kimi K2.6, 已就位 / 一键部署 OpenClaw")
  no longer counts as answer content.
- Drop the class-based loading-indicator probe entirely. The previous
  global [class*="loading"]/"stream"/"typing"/"spinner" sweep matched
  K2.6's always-on text-stream wrapper and held busy=true forever, which
  caused kimi_query_timeout even after the assistant turn had fully
  rendered. The textual busySignalsPattern (思考中/搜索中/生成中…) is
  the actual semantic signal and survives any UI rename.
- Surface a capacityNotice from the assistant turn when Kimi shows its
  short capacity-exhausted message ("算力不够 / 请稍后再试"). The top
  level falls back to it when answerText is empty so the SaaS pipeline
  records the user-visible message instead of an unknown row, with
  capacity_limited / capacity_notice flagged in raw_response_json.

All filters lean on HTML form / ARIA semantics and visible text rather
than Kimi-specific BEM classes, so they survive future redesigns.
