* docs(agents): add step-by-step workflows with posting and label procedures
Add numbered step-by-step workflows to all four automation agents
(pr-review, reproduce-issue, summarize, triage), each with an explicit
comment-posting sub-procedure: draft once, post via gh, capture result,
verify by reading comments back only, and retry once on failure.
pr-review also gains a Labels section that applies confidence:* and
risk:* labels matching the review scores, removing stale labels first
to avoid stacking. merge-conflict:true is left to its dedicated action.
triage renames its label-selection steps to Category 1-5 to avoid
colliding with the new workflow step numbering.
* fix(agents): avoid duplicate comments after ambiguous posts
