docs(skills): triage fire opens with by-name tool loading — stop the 55-schema ToolSearch ticket on self-retire rounds (#10104) (#10105)

One clause in the 分诊座位职责 section: the opening mutex-check /
self-retire probe loads only list_issues + issue_read via the select:
form of ToolSearch; the full toolset loads only after the round is
judged live. Applies to triage fresh sessions only; standing execution
seats and devs are exempt. Acceptance: idle round ~120k -> under ~40k,
read back by the triage seat's next self-measurement.

Net +1 line, paid from the file's 1-line headroom (681 -> 682/682).

Fixes #10104
