Live lifecycle board (grid<->board toggle) plus an assignee-swimlane plan
board that groups follow-up re-runs of one goal into a single xN card.
Custom right-side detail/goal panels with markdown output. Fixes plans
being persisted under the per-run trace id so the board actually populates.
Closes#385
Add /wiki/pages row to endpoint table and a new "Wiki knowledge-base
reference ([[slug]] picker)" section explaining the directive-text
mechanism, query parameters, visibility rules (synthesis excluded,
100-page cap, KB-scope fallback), and curl examples (zh + en).
Follow-up docs for the wiki picker endpoint shipped in this PR.
Add /skills row to endpoint list table, note optional agentId on /stream,
and add a new "Skill invocation (slash picker)" section explaining the
directive-text mechanism with curl examples (zh + en).
Follow-up polish for the /skills endpoint shipped via PR #374.
