Why

Several docs pages grew by appending a paragraph per feature or performance change. They mixed implementation detail (cache files, batching, storage internals) and history notes into user pages, with little structure, so they were hard to read.

Changes

• Restructured six pages around what users do, with examples and tables: Semantic Compilation, sqb compile, Testing, sqb janitor, Recall and Project Configuration.
• Removed internals users can't act on, history wording ("earlier releases", "as before", upgrade notes) and rules duplicated between pages (linked instead). Kept every flag, setting, default, limit, code and message.
• Corrected the janitor's source-schema block to say it applies in direct mode.
• Added website/STYLE.md, a short docs style guide, and an AGENTS.md section requiring docs changes to edit pages into shape rather than append.
• Regenerated the skill reference copies of the changed pages.

Verification

• Website build passes; every in-site anchor link resolves.
• Each page reviewed against its previous version and, for changed claims, against the source.
• Public-repository hygiene scan passes.
