Optimize inefficient code patterns in app.js and cla-mark.yml

[Copilot]

Summary

Fix performance inefficiencies: repeated object/array allocation in hot paths and sequential API calls that can run in parallel.

app.js

• Move nickColors array out of nickColorClass() — was recreated on every call
• Move htmlEscapeMap out of escapeHtml() — was recreated on every regex match

cla-mark.yml

• Parallelize ensureLabel() calls with Promise.all() — labels are independent

// Before: object created per character match
function escapeHtml(s) {
  return s.replace(/[&<>"']/g, (c) => ({ '&': '&amp;', ... }[c]));
}

// After: single allocation
const htmlEscapeMap = { '&': '&amp;', '<': '&lt;', '>': '&gt;', '"': '&quot;', "'": '&#39;' };
function escapeHtml(s) {
  return s.replace(/[&<>"']/g, (c) => htmlEscapeMap[c]);
}

Ethics & Safety checklist

• Change complies with ETHICS.md (Non‑targeting & benevolence)
• No PII or sensitive trait inference
• No scraping of gated/paid content; no attempts to bypass DRM or rate limits
• User‑visible or external actions are explicitly approved by a human reviewer (or N/A)

Security checklist

• No secrets committed; uses platform secrets where needed
• Logs do not include secrets, hostnames, or other sensitive details

@copilot could you help us solve "// Before: object created per character match
function escapeHtml(s) {
return s.replace(/[&<>"']/g, (c) => ({ '&': '&', ... }[c]));
}

// After: single allocation
const htmlEscapeMap = { '&': '&', '<': '<', '>': '>', '"': '"', "'": ''' };
function escapeHtml(s) {
return s.replace(/[&<>"']/g, (c) => htmlEscapeMap[c]);
}" this please? =)
