disk/speaker: drop static-import ?v= cache busters
The oven bundler's rewriteImports regex strips ?query suffixes from
relative imports, but a stale snapshot on the live oven server is
preserving them — packed pieces emit `import * as l5 from
"lib/l5.mjs?v=20260330-runtime-support"`, which fails browser import-map
resolution since map keys are query-less ("Failed to resolve module
specifier").
Cache busting for these built-in modules is already handled by the
service worker, the lith deploy hash, and per-bundle blob URLs.
Removing the queries makes the bundle robust regardless of which
bundler version the oven is running.
