Runtime-served custom emojis from Fly.io volume (no redeploys)

Reduce emoji pulse + Markdown links in status text

fix: refine aesthetic details for better UX

- Remove bounding rectangle glow on handle hover, keep text-only glow
- Make set button hover use dynamic accent color instead of hardcoded blue
- Reduce pulsating glow intensity on status emoji by ~10%

The repo is 'status' not 'status.zzstoatzz.io'

feat: add HTML/JS linting and bug report button

- Return loaded values from initSettings to use after API/localStorage load
- Use the actual loaded accent (respecting API -> localStorage hierarchy)
- Matches the pattern used in feed.html for settings management

Move updateActivePreset call after initSettings and use localStorage value

The previous null check fix had incorrect indentation that broke JavaScript execution.
Fixed indentation for both emoji picker and clear picker event handlers.

- Add HTML syntax checking with xmllint to pre-commit hooks
- Add JavaScript syntax validation with node -c
- Add JSON validation to catch syntax errors before deployment
- Add floating bug report button on all pages
- Bug button collects context (page, theme, viewport) and opens GitHub issue
- Responsive design for mobile devices
