perf(image): drop chromium from the server image — 875 MB to 212 MB
Chromium and fonts-liberation were 758 MB of an 875 MB image: 87% of the server
image was a browser it never launched.

It was installed for the Slice 6 mission PDF renderer, which no longer exists —
every call site passes `render_pdf: false` because markdown is the deliverable —
and NOTHING in the workspace reads the CHROMIUM_BIN this image set. The only
Chromium the platform actually uses is `browser.goto`, which runs it inside the
agent's dedicated egress-enabled BROWSER container
(cm-runtime/src/tools/browser.rs), never in the server.

Measured on gw-04: 875 MB -> 212 MB. The remainder is debian-slim (75 MB), git
and its dependencies (~95 MB) and the server binary (42 MB). git stays: research
topic clones shell out to it, which is why this image left distroless in the
first place.

Verified in the slimmed image: git 2.39.5 present, CA bundle present, chromium
absent, binary executable, templates and all 8 skills shipped.

That 663 MB was paid on every deploy, every registry push, and every air-gapped
bundle.
