Amendment 3: scoop install and brew install both verified end-to-end on
real Windows + macOS (install + run), resolving Amendment 2's unverified
caveats (incl. the HEAD:main push).
Records the root cause + fix for the Homebrew 403: Gitea (>=1.25)
303-redirects release downloads to a method-bound SigV4 presigned S3 URL;
brew resolves with HEAD, captures the HEAD-signed URL, then GETs it -> 403
(GET-only tools are unaffected). Fixed by a server-side Caddy rule that
answers HEAD on release-download paths directly (200, no redirect) so the
download GET re-runs the redirect fresh. That rule lives in the Gitea edge
config, NOT this repo - documented so a server rebuild doesn't silently
break brew. Includes the reference Caddyfile block.
Also notes the ad-hoc mac signature runs fine via brew; Developer-ID +
notarization stays parked on the Apple org conversion. Remaining D3: winget.
