Two unrelated console errors.

effect_update_depth_exceeded — mine, from the previous commit. The live-update
effects both read and wrote the same state: FleetMap's health patch builds a
new `graph` object every run, and EntityDetailContent's refreshExecutions()
assigns a fresh `executions` array. Svelte tracked those reads, so each write
re-triggered the effect, which wrote again, until it gave up. The effects now
depend on liveEvents alone and do their work inside untrack(). Applied to all
four live effects, including the two that happened to settle on their own —
relying on "applyHealthEvent returns the same reference when nothing changed"
to break a feedback loop is far too subtle to leave implicit.

SyntaxError: expected expression, got '<' — pre-existing, and unrelated to the
live-update work. index.html loads /wails/runtime.js unconditionally; that file
only exists inside the Wails desktop wrapper, which serves the same dist/ from
its own asset handler. In a browser it is missing, and the SPA fallback
answered it with index.html — so the browser parsed "<!doctype html>" as
JavaScript on every single page load. The web Caddyfile now returns a real 404
for /wails/*, and more generally serves asset extensions without the SPA
fallback: a missing .js or .css answered with HTML is always a confusing parse
error rather than an honest 404.
