feat: scaffold newsfeed — user-controlled news feed

A self-hosted feed where the user owns the ranking: per-source and signed
per-interest weights, decayed by recency, via a transparent deterministic
scorer. Content is sourced algorithmically (worker RSS/Atom polling) and
agentically (per-user API tokens POSTing candidates to the ingest endpoint).
Single-user today, multi-user by construction (every row keyed on user_id).

Rust cargo workspace + Vite/React/SWC/TS SPA:
- newsfeed-entities: DTOs (ts-rs bindings -> web/src/api/bindings)
- newsfeed-core: ranking, auth primitives, ingest, data-access ports
- newsfeed-data: SQLite adapters (sqlx, runtime queries)
- newsfeed-api: axum REST/JSON daemon
- newsfeed-worker: RSS polling + rescoring loop
- web: responsive, mobile-first SPA (React Query, generated types)

Deploy (Gitea Actions, build static musl + SPA, rsync as gitea_ci):
api+worker -> slartibartfast, SPA -> oolon (nginx serves + proxies /v1).

Deliberate deviations from house conventions (documented in CLAUDE.md/readme):
- SQLite instead of Postgres; api+worker co-locate sharing one DB file.
- Runtime sqlx queries instead of query! macros (SQLite dynamic typing;
  keeps CI database-free).

Verified end-to-end: auth, token ingest, interest-weighted ranking, signals,
pagination (curl + browser); cargo fmt/clippy -D/test and pnpm build/lint pass.
