Address important live README review findings

[VolkerChristian]

Scope

Refines the existing Install route-button and compact-page-banner work, and addresses the important findings from Claude's live GitHub README review. Four participating repositories only: snode.c, mqttsuite, AISuite and CodexUI; .github owns the shared frame and generated organization profile. Not merged.

Important review fixes

• One clear repository return per supporting page: linked quarter-height banner with repository-identifying alt text; duplicate Back blocks and unused Back SVGs removed. Original full-size root artwork unchanged; every supporting Markdown file still receives the owner-requested banner.
• Security boundaries surfaced (broker auth/ACL limitations, protected MQTTStore credentials, durable pasted-image retention); user guides separated from historical implementation/qualification records without deleting evidence.
• One complete echo tutorial and a true application inventory; source-verified operator logging, bridge/mapping field semantics, TLS/private-network WSS templates, external app-server and source SDK consumption instructions.
• Compatibility and candidate-release wording distinguish source targets/version floors from proven binary compatibility or publication. API buttons enter verified legacy class indexes, labelled as snapshots rather than current installation guidance.
• Compact three-column organization catalog combines real CI/release data; blank releases use a dash, unavailable badges are not invented. Badge separators and pre-menu redundant content reduced. Shared frame matches these responsibilities.

Verification

• All 72 Markdown documents in the four repositories rendered with GitHub's Markdown API; all local links/anchors/images checked, including the 68 supporting-page banners.
• Root first-success code fences unchanged; full worked echo code transferred intact; original root banners/chips/screenshots byte-identical.
• python3 tools/snodec_sync check, python3 -m unittest discover -s tests -v (33 passed), and generated-profile drift check passed in .github.
• TLS bridge-network JSON validated against the actual bridge schema. Built AISuite WSS local/TLS help confirms listener, host/port, cert and cert-key options; source inspection backs other new commands/semantics. Full remote broker, authenticated Codex, private VPN/WSS and desktop qualification were NOT run; operator placeholders must be supplied and tested.
• No workflow, package pipeline, secret, release tag, licence, manifest or AGENTS.md changes. No CI hand dispatch. Failing workflow statuses are not hidden or fixed by this docs change.

Accounting for this review-fix follow-up

Production-source physical lines: +8/-10 (existing profile renderer +4/-4; obsolete CMake comment corrected +4/-6, executable CMake byte-for-byte equivalent after removing comments/blank lines). No runtime/build behavior change and no production-code growth. Test source: +37/-7, preserving original checks and adding compact-status regression coverage. Documentation/static assets: +1266/-1614; historical record extraction reuses the existing banner assets.

Claude's main report and visual supplement informed this change; its full completion supplement hit its session quota. This is not a claim of fresh Claude approval. Optional root-banner/naming redesign and CI/runtime repairs are outside this scoped follow-up.

Final mobile check

Long repository/kind labels receive GitHub-supported zero-width break opportunities in display text only; catalog identity and canonical URLs are unchanged. This fixes the remaining phone-width overflow without repository-specific exceptions. The actual published organization preview was visually checked at 390 px. The renderer retains one identity authority, and no workflow behavior changes.
