Leo, 2026-10-24: "why arent nightlies up yet".

Problem

nightly-next run 40073451596 at 39e07dce42 failed at "Build the web bundles (cmux-next)":

error: the agent pane imports webviews/src/agent-session/acpmux/harnessStatus.css but build-agent-pane-web.sh does not add it to the page's styles

HarnessStatusCard.tsx (11c3f51, #24796) imports harnessStatus.css, but the agent pane build script never concatenated it. This is the same class of base red as DispatchCard.css (b9df372) and ContextSection.css (#23939). #24161 (open) would derive the list from the imports for good.

Fix

Add $SRC/acpmux/harnessStatus.css to the pane's styles.css concatenation, next to harnesses/harnesses.css. The file has no @import, so a plain cat is right.

Verification

The script's own import check (the imported-sheets loop) is what failed. This PR's "cmux-next web bundles" job runs it. No app build on big-red, per the rules.

Summary by cubic

Fixes the cmux-next nightly build failure by bundling harnessStatus.css into the agent pane's styles. HarnessStatusCard imports the stylesheet, but the build script never concatenated it, so the script's import check rejected the web bundle step.

Written for commit c4d4ffe. Summary will update on new commits.

HarnessStatusCard (11c3f51, #24796) imports harnessStatus.css, but
build-agent-pane-web.sh never added it to the page's styles, so its
import check refused the web bundle step. This failed nightly-next run
40073451596 at 39e07dc in 'Build the web bundles (cmux-next)'.

Closing: feat-cmux-next already has this fix in 1be6de3 (same one-line addition of harnessStatus.css to build-agent-pane-web.sh), so this PR now conflicts and adds nothing.
