fix(ci): compact commit list + bigger token budget for release announce [skip ci]

The v3.0.2 announce (PR #263, 45 commits) never reached Discord: the
changelog prompt carried every commit body (52 KB), deepseek-v4-flash
spent its whole 6000-token budget reasoning, returned empty content and
the guard aborted the run before posting.

Past 8000 chars of commit detail we now send hash + subject only (52916
-> 3699 chars on that range), raise the budgets to 32000/16000, and retry
once with double when content still comes back empty. Also log
finish_reason and completion_tokens so the next empty answer is
diagnosable from the run log alone.
