Fixes from the code-review workflow (7 findings): page the poll cursor past the
100-msg window (no false timeout behind bot/overflow messages); honor 429
retry_after and bail fast on permanent Discord errors (10003/50001/...) instead
of burning the timeout; status-check overflow follow-up chunks (warn, don't
silently truncate); clamp --read limit safely (guard >64-bit overflow); add
--wait --after for precise resumption; DRY the newline-trim; set LC_ALL=C.UTF-8
for codepoint-safe slicing. SKILL.md gains the tested bot capability/limit map
(can: post/read/edit-own/react; cannot without a grant: delete/archive/unlock/pin)
and a robustness section.
