fix(wasm): commit gosqlx.wasm to git to fix production playground 404 (#423)

Root cause: Vercel's GitHub auto-deploy fires on merge to main but cannot
build the WASM binary (it's a Go build step not in Vercel's build). The
auto-deploy overwrites the website.yml CI deployment (which has WASM),
resulting in /wasm/gosqlx.wasm returning HTTP 404 in production.

Fix:
- Remove gosqlx.wasm from .gitignore so it ships with every deploy
- Add CI step to auto-commit rebuilt WASM when wasm/ source changes
- Bump website.yml permissions: read → write (needed for the git push)

The committed WASM (6.5MB, built 2026-03-16 from v1.13.0 source) is
current — no changes to wasm/ source since that build date.
