feat(mavweb): /ecosystem page consuming Nexus/Praxis/Hexis + shell fixes

Add a read-only /ecosystem page that consumes the sibling services'
JSON APIs (Nexus entities, Praxis attention, Hexis capabilities),
fetched concurrently with honest per-panel error states. Siblings stay
headless — mavweb is their human surface (arch §16). Wired via mavweb
-nexus/-praxis/-hexis flags; mavweb joins the ecosystem compose network.

Fix mobile horizontal overflow across all pages: .content is a flex
child with default min-width:auto, so it refused to shrink below the
tables' intrinsic width. min-width:0 lets wide tables pan inside .scroll
instead of dragging the page sideways. Verified via CDP geometry check
(scrollWidth === clientWidth at 430px).

Also includes in-progress Ethos UI redesign, ecosystem deploy compose,
and planning docs.

-1. **Foundation + router** — router-as-LFM, turn the engine ON (resident
-   sub-1B), verify notes+reminders actually round-trip, date/number TTS
-   normalizer, wire telegram reach. After this she's a trustworthy plain
-   assistant.
-2. **On-demand 4B reasoner** — summon/idle lifecycle + router escalation path.
-3. **Digestion worker** — reflection, proactive suggestions, memory
+1. **Foundation + router** — completed shared llama-server client, router,
+   fallback, replier, TTS normalization and telegram reach.
+2. **Qwen3 resident checkpoint** — finish RU CPT, pass the raw-vs-CPT gate,
+   jointly SFT persona/router contracts, merge, quantize and deploy.
+3. **Main features** — reflection, proactive suggestions, memory
    consolidation, RAG read-back.
-4. **Embodiment** — voice quality (deferred).
+4. **Deferred work** — larger reasoner, custom Piper voice and other expansions.
