docs: the README shows the product before the philosophy

[vicenteliu]

What

Both READMEs restructured for first-visit scanability, with every factual claim preserved:

• Visuals first — "A quick look" (web UI screenshot + the TUI gif regenerated in fix: the TUI tour gif stops racing its own workers #213/fix: ingest stops reading the fixture format's own metadata as knowledge #217) moves up right under the intro paragraph.
• One-line TOC after the intro.
• Highlights condensed — the six essay-length bullets (Memory, Consultation, Asset inventory, Runtime Skills, Proposed actions, Knowledge bundles) become 2–4 line summaries with [details](#…) anchors.
• New "Design notes" section after Quick start carries the six essays verbatim — the reasoning stays in the README, it just no longer stands between a visitor and Quick start.
• zh-CN mirrors the structure exactly; CJK anchors verified against github-slugger semantics.

Review

Ran /code-review high on the diff before this PR. It found 8 real condensation losses, all fixed in both languages:

1. Intake bullet had lost "(no public endpoint)" and "(no field is ever touched)" — restored.
2. Multi-user bullet had lost "never the database" — restored.
3. Multi-provider had lost "when a provider errors" and "remove or upgrade models" — restored; an accidental "declare"→"pin" drift reverted.
4. WeCom had lost the group-robot vs self-built-app distinction — restored.
5. Memory bullet's "anchored to an Asset or site" mis-stated the model — back to "up to two anchors (an Asset, a site)".
6. Stale adjacency: Asset inventory read "the one domain OpsPilot owns" a screen away from Memory's "second owned domain" — now "the first domain OpsPilot came to own".
7. TOC omitted License — added.
8. (One pure-style candidate was dropped by the reviewer as no-effect.)

The reviewer also verified: all 28 new anchor links resolve (including CJK slugs), the six moved essays are word-for-word, no external file links into README anchors, and CONTEXT.md terminology is respected.
