Docs: complete end-user and maintainer documentation

[hyperpolymath]

Goal

Complete human documentation across the end-user and maintainer audiences. (The developer quickstart was filled in #37; deep dev docs already exist in docs/developer/ABI-FFI-README.adoc.)

End-user (QUICKSTART-USER.adoc is an unfilled template)

• Fill QUICKSTART-USER.adoc with a real worked example.
• Tutorials: GDPR consent retrofit, WCAG 2.2 compliance, i18n retrofit.
• wokelangiser.toml manifest schema reference (with examples).
• FAQ / troubleshooting (incl. "why doesn't generate produce output yet?" — pre-alpha).

Maintainer (QUICKSTART-MAINTAINER.adoc is an unfilled template)

• Fill QUICKSTART-MAINTAINER.adoc (packaging via Guix/Nix/container).
• Release runbook (version bump, CHANGELOG, tag, publish).
• Dependency-update policy (Rust/Idris2/Zig version bounds, cargo audit cadence).

Notes

• docs/ is the canonical home; the GitHub wiki is empty (docs/wikis/ is a stub) — decide whether to retire the wiki references or wire up a sync.
• theory/, whitepapers/, reports/ sections are intentional sketch stubs — leave until the research roadmap firms up.
