chore(release): v3.22.1 — retitle unpublished v3.22.0 + fold in #161 (Windows resolve) and #152 (Sonnet 5) (#169)

v3.22.0 (#166) was merged but never tagged; #161 and #152 then landed on main,
so the prepared release no longer matched HEAD. Owner opted to renumber: the
v3.22.0 CHANGELOG section becomes v3.22.1 (with an explicit version note),
gains entries for #161 and #152, and the tag will be cut at this release
commit — no tagging of historical commits needed. package.json 3.22.0 → 3.22.1.

Semver note: still a minor-family bump from 3.21.1 (features: #156/#158/#159,
plus #152's new model entry); 3.22.0 is simply skipped — semver requires
increasing versions, not contiguous ones.

Release-kit walk (delta vs #166's walk): #152 → README "Available Models"
table row already present (added in #152 itself) + models.json is the SPOT;
#161 → no new env var/endpoint; README §Windows guidance unchanged (Windows
support deliberately NOT advertised until #167 lands + real-Windows E2E).
