Adopt Simplified Technical English across docs and add compliance checks

[abramdawson]

Rewrite all 53 existing pages toward ASD-STE100 Issue 9, preserve URLs and legacy anchors, and add an internal authoring registry of 164 project terms.
Add blocking Markdown/MDX checks, 31 regression tests, build and editorial-review workflows, and contributor guidance, with corrections checked against backend, CLI, contract, and web-client source.

• I followed CLAUDE.md and STE.md
• I checked new or changed behavior against product source; historical team usage and provider compatibility claims still need maintainer confirmation
• I defined technical terms in the internal registry and kept reader definitions on canonical feature pages
• pnpm build passes, including prose checks and 31 checker/review tests
• I read rendered pages and checked all 53 Markdown twins and 87 page and anchor targets

A maintainer must review the current commit against ASD-STE100 Issue 9 and approve with STE review complete; required GitHub checks and approval rules must be activated after merge.
Passing automation alone does not establish compliance.
