createSidecarProxy arrived with the wallet but nothing else moved onto it, so five sidecars
still carried their own copy of the same two files: a sidecar-server.ts that remembered a
port announced as `<name>:server`, and a router.ts that forwarded the subpath. Byte for
byte identical once the app name was normalised away — which is exactly what the factory's
own header said it existed to end.
headscale, transmission, invoiceshelf, slskd and music are now wallet-shaped: create the
proxy, export the router and the URL getter. 386 lines deleted against 163 added, and the
five feature directories go from ~70 lines each to ~18.
Two deviations were real and moved INTO the factory rather than being dropped, because both
are HTTP concerns rather than app knowledge:
- Range and If-None-Match are now forwarded for every sidecar. music needed both (seeking,
and ETag revalidation returning a cheap 304 instead of a cover image) and slskd needed
Range. Forwarding them everywhere costs nothing and removes the reason to hand-roll.
- timeoutSeconds, used only by music at 1800. A from-scratch reindex holds the proxied
connection open for minutes with no bytes flowing, which the 60s idle timeout would drop.
It applies to the whole prefix — the proxy must not know which of a sidecar's routes are
slow.
The five side-effect imports in hono.ts are gone with them: the port listener now registers
when createSidecarProxy runs inside the router this file already imports. Vault keeps its
hand-rolled pair and its side-effect import — it is off-limits by standing instruction, and
is the one sidecar this commit deliberately does not touch.
