Gitea returns dates like 2026-08-12T11:09:13+02:00. The default JSONDecoder
date strategy expects a Unix timestamp number, so decoding any Date? field
threw and the whole [PullRequest] array failed — the inbox showed no PRs.
Add a shared decoder with a custom ISO8601 strategy (with and without
fractional seconds) and use it for all get/post decoding.
Multi-repo PR inbox, review (approve/request changes/comment), merge with
gating toggle, read-only diff viewer, and Gitea Actions check status with
one-tap re-run. Ships unsigned via the iMac runner to the SideStore source.
