docs: deep audit pass — fix drift across every doc, rebase coding-standards on /unslop

Each doc verified against current code; stale claims fixed in place.

- architecture: handshake/binary-frame/route/module-table corrections
- data-model: atomic-write claim narrowed, missing daemon files/fields added
- development: db:query removed (SQLite/Drizzle gone), tmux→concurrently+portless, PASEO_HOME split
- unistyles: withUnistyles(Icon) is the dominant pattern; new Animated.View+dynamic-styles iOS gotcha
- SECURITY: bearer-token auth, DNS-rebinding allowlist semantics, ephemeral phone keypair, wire format
- glossary: Project-checkout rename has shipped
- providers: claude-acp not built-in, Pi/mock, async isCommandAvailable, interface drift
- coding-standards: rewritten as compressed /unslop adaptation
- product/release/testing/custom-providers/android/mobile-testing/ad-hoc-daemon-testing/file-icons/design: smaller corrections
