fix: prevent filter row overlap

[pilipilisbot]

Fixes #41.

Summary

• gives the Actor filter a two-column desktop span so it no longer collides with the Intent selector
• lets filter grid items shrink inside their columns with min-w-0, keeping mobile stacked and overflow-free
• rebuilds the packaged dashboard assets

Post-merge cleanup complete.

• PR fix: prevent filter row overlap #42 merged at 2026-05-25 12:07 UTC with merge commit 0f44f2fe3f2d50b723e2c44bc51aaf60120f2dae.
• Post-merge tests and release runs both passed on the merge commit: https://github.com/pilipilisbot/github-agent-bridge/actions/runs/26399676411 and https://github.com/pilipilisbot/github-agent-bridge/actions/runs/26399676291
• Synced the canonical checkout to clean main at release tag v0.18.4 (868abaf).
• No dedicated PR worktree existed; the only checkout was canonical, so I left it in place and deleted the stale local fix-overlapping-user-filter branch after GitHub deleted the remote head.
