Phase 3a of the Clubhouse/nests integration. Adds a new KMP module
`nestsClient` (Android + JVM targets) that owns the HTTP control plane
for talking to a nests audio-room backend. No transport/audio yet —
that arrives in 3b with WebTransport + MoQ.
Surface:
- `NestsAuth.header(signer, url, method)` signs a kind 27235 event via
Quartz's existing HTTPAuthorizationEvent and returns a ready-to-use
`Authorization: Nostr <base64>` header value.
- `NestsRoomInfo` data class + tolerant JSON parser (ignores unknown
fields so newer nests server revisions don't break older clients).
- `NestsClient.resolveRoom(serviceBase, roomId, signer)` calls
`<serviceBase>/<roomId>` with the signed NIP-98 header and returns
the MoQ endpoint + token the audio layer will need.
- `OkHttpNestsClient` (jvmAndroid) is the default implementation
shared between Android and desktop JVM.
Tests:
- `NestsRoomInfoTest` (commonTest) covers full/minimal payloads,
unknown-field tolerance, missing-endpoint rejection, and URL
construction edge cases.
- `NestsAuthTest` (jvmTest) signs a real 27235 event, decodes the
base64 back through Quartz's JacksonMapper, and asserts the
signature verifies and the url+method tags bind correctly.
