TinyGo 0.41.1 and earlier vendor tinygo-org/net@e54965e, whose net/http
js/wasm overlay (roundtrip_js.go) calls the private t.roundTrip fallback
removed from Go 1.25+/1.26 net/http, so `pnpm run build` fails to compile
on Go 1.26 (tinygo-org/tinygo#5467). No released TinyGo carries the fix
yet: it landed in tinygo-org/net@1026408a on 2026-04-27, after 0.41.1
shipped 2026-04-22, and is already on TinyGo's dev branch.
Keep Go 1.26 and apply the exact upstream fix in CI before the build:
- .ci/tinygo-net-roundtrip.patch: byte-exact tinygo-org/net@1026408a diff
(its parent e54965e is the commit 0.41.1 ships), targeting
src/net/http/roundtrip_js.go.
- ci.yml: new "Patch TinyGo net/http (temporary)" step applies it to
$(tinygo env TINYGOROOT) via `git apply`, failing loudly on drift.
- .gitattributes: force LF on *.patch so `git apply` works on the Linux
runner regardless of the committer's platform.
- README: document the temporary patch and its removal condition.
Temporary: remove the patch and the CI step once a TinyGo release later
than 0.41.1 ships the net fix. Tracking #26.
