Every plain `sh tool/build.sh` invocation now reasserts a relative symlink
website/releases/<tool>_alpha.html → ../../<tool>/dist/<tool>.html so the
alpha hyperlinks always serve whatever dist currently holds. Idempotent — git
sees no churn on rebuild. `--release alpha` still wins by overwriting the
symlink with a real "alpha · <date> · <sha>" file; the next plain build
re-symlinks it.
Five existing alpha files become typechanges (regular file → symlink) — the
one-time migration cost. The reassertion survives deployment because the
website is served directly from the working tree.
