Add /track/lyricsUrl (signed RPC, method name "tracklyricsUrl") plus
the CDN document fetch through the offline choke point. Wire shapes
were validated against live captures (2026-06-10) and diverge from the
inferred yaml: numeric track_id in the step-1 envelope, CDN document
wrapped in {translation_langs, publishers, writers, original}, "wsync"
word-synced discriminator instead of "lsync" (per-word timestamps),
plain lines as objects, and miss = HTTP 404 error body mapped to a
typed Ok(None) instead of an error. Unit tests deserialize fixture
excerpts of the captures; examples/lyrics_probe.rs is the read-only
live probe used for the capture.
Also expose qbz_credentials::load_oauth_token_from_file so a stale
keyring entry cannot shadow the authoritative encrypted token file.

Startup blocked on Qobuz's ~7 MB web bundle download with no cache or
timeout, so a slow CDN left the app on a blank screen for 25-30s before
the login screen appeared. Cache the extracted tokens on disk (keyed by
bundle version), apply them instantly on warm starts and refresh in the
background, and bound the cold fetch with a per-request timeout + retry.
The legacy api client shares the same cache. Emits BundleFetchStarted so
the UI can show a connecting state on the first run.

Create the foundational workspace structure for the multi-crate
architecture refactor. This phase establishes placeholder crates
that will be populated in subsequent phases.
Crates created:
- qbz-models: Shared types, events, and traits (Tier 0)
- qbz-audio: Audio backend system (Tier 1)
- qbz-player: Playback engine and queue (Tier 1)
- qbz-qobuz: Qobuz API client (Tier 1)
- qbz-core: Orchestrator (Tier 3)
All crates compile successfully with placeholder implementations.
The workspace uses shared dependencies via workspace.dependencies.
