Detail-page pipeline + log panes weren't updating without a manual
refresh. Root cause: the integrity attribute on htmx-ext-sse@2.2.2
in layout.templ was wrong, so the browser refused to execute the
script (SRI enforcement is silent — no user-visible error unless
you open devtools). htmx core loaded, boosted nav worked, forms
worked — but sse-connect/sse-swap were inert because the extension
never registered, so no EventSource was ever opened.

Replaced the claimed hash (Y4gc0CK6...) with the real one
(fw+eTlCc...) computed via
  curl -sL https://unpkg.com/htmx-ext-sse@2.2.2 |
  openssl dgst -sha384 -binary | openssl base64 -A

Added sse_e2e_test.go as a regression canary that mounts the real
chi router (RealIP + Recoverer + Logger middleware), opens
GET /events, publishes a tile-update via Runner, and asserts the
event lands on the wire. Server-side unit tests only verified
rendered HTML — this one covers the full publish→wire path, which
is what the next regression in this area will hit.
