feat(telemetry): greenfield dsh-sdk telemetry modules

Add @deepseek-ai/dsh-telemetry, a launcher-side (non-plugin) library for the
ConsentResolver (parses cordis.yml consent + DO_NOT_TRACK/CI), buildTelemetryPayload
(redacted cordis.yml + package.json full content, never .env), getOrCreateAnonymousId
(random UUID in a per-machine global config file), and TelemetryReporter
(fire-and-forget, never blocks or crashes the command).

Endpoint is a fixed .invalid placeholder pending the real endpoint. Launcher
dispatch wiring and the helper feature-catalog entry are intentionally out of
scope. Registers the package in tsconfig references, the module graph, and the
README model-experience audit map. Per-file 100% coverage.
