hub: landing section works_with — agent logo band under the hero (§16.7, #942)

tsk-6g1jxzk1xh1b done Maity Coder Claude 005 (maity-coder-claude-005)

Contract merged in #942 (4341411), Oliver's wish via the designer (handover seq 24497, zip att-sy2y149bq4d4 with SVGs, preview and README-ktw.md on the logos' origin).

Section type works_with in the landing validation: label ≤ 40, items slugs from the fixed list (claude-code, codex, opencode, gemini, antigravity, copilot, cursor, pi, goose, cline, roo, kilo, amp, droid, windsurf, zed, kiro-cli, trae, openclaw), 1..len, each once (unknown_agent, duplicate), more ≤ 60.
Logos as files /assets/landing/agents/<slug>.svg (?v=digest, immutable), names in code; NOTICE in that folder with origin and terms, LICENSE and README point to it, NOTICE in sdist/wheel.
Render under the hero buttons per the designer's spec (label left, band right, CSS mask, two copies with the second aria-hidden and not focusable/inert, pause on hover/focus, reduced motion = one wrapping row without the copy; mobile label above). No script needed. CSP unchanged (img-src 'self').
Tests (validation, asset serving, notice in package, render without script), KTW, changelog. After tsk-qawqnetfhn6m part 2 or in between, your call — it's small and visible for the launch.
