Sync skill counts for frontend-slop-audit

[DROOdotFOO]

Companion to agent-skills#12, which adds skills/frontend-slop-audit/ and two design-ux sub-files (web/motion.md, web/design-system-selection.md).

Documentation-only. Updates the skill accounting that this repo tracks for the merged host inventory.

Location	Change
CLAUDE.md skill accounting table	agent-skills skills/ 58 -> 59; loaded by Claude Code 60 -> 61
CLAUDE.md code-pattern table	design-ux row now mentions motion
CLAUDE.md workflow skills	40 -> 41 total; frontend-slop-audit named
README.md stack table	Claude Code (60 skills) -> (61 skills)

~/.agents/skills-upstream is a separate clone rather than a symlink to the working copy, so these counts describe upstream main and only become true once agent-skills#12 merges and chezmoi apply --refresh-externals re-derives the externals.

Left unchanged: the curated 6-skill highlight list in home/private_dot_claude/CLAUDE.md.tmpl. It names only domain/reference skills (claude-api, droo-stack, noir, solidity-auditor, zk-x-ray, ethskills) and no workflow skills at all, so it is a deliberate subset rather than an inventory.

Manual testing

• Counts re-derived against the source of truth rather than incremented blindly: ls -d ~/CODE/agent-skills/skills/*/ gives 60 dirs, of which one is the cancer-predisposition-variant-analyst submodule, so 59 portable; ~/.agents/skills-extra/ holds 2 (hf-cli, virtuals-protocol-acp); 59 + 2 = 61
• Confirmed current installed state still reads 58 upstream, matching the pre-merge numbers this PR replaces
• Branched off main, not the in-flight feat/scoped-codex-target branch behind PR Add scoped Codex configuration target #20
• No template, script, or .chezmoiexternal.toml changes needed; the externals clone picks the new skill up automatically

Merge order

Land after agent-skills#12.
