docs(requirements): tighten public api rows

Add explicit northstar ring fields to public_api requirements, remove planning wording, and split page-boundary guidance from beginner escape-hatch guidance.

 - Use the same Workout command surface for tests, production build, and mobile release: `cargo run -p hemx-xtask -- workout test`, `cargo run -p hemx-xtask -- workout build`, `HEMX_WORKOUT_ORIGIN=https://workout.example.com cargo run -p hemx-xtask -- workout mobile-release`, and `HEMX_WORKOUT_ORIGIN=https://workout.example.com cargo run -p hemx-xtask -- workout mobile-verify`; Android/iOS SDKs, store submission targets, and signing remain external blockers, not repo-owned secrets. req: examples/006 req: examples/011
 - hemx core stays small: effects, typed ids, registries, and wire schema only; keep features in core only when they fit typed resources plus EffectBatch ops. req: laws/001
 - Routing, auth, sessions, transport, transitions, sync, and storage belong in integration/user crates.

 - Typed partial swaps should stay expressed as generated target plus rendered partial plus swap kind, not selector-driven rerendering; HTTP, page navigation, push, and island behavior adapt around that loop, and docs should layer new primitives progressively. req: canonical_authoring/002 req: canonical_authoring/014 req: modes/001 req: progressive_disclosure/004 req: page_swap/001 req: page_swap/002 req: page_swap/003
 - `examples/html_examples` is the copy-paste HTML pattern gallery for htmx-style examples; keep exact htmx URL slugs visible while translating behavior to boring `.heml`, generated resources, and server-owned Rust state, not HTMX syntax or selector targeting.
