Release v0.1.1 — Polish: level meters, timer in menu bar, app icon · BozhengLong/meetrec

A polish release. No new core functionality — everything from v0.1.0 still works the same way — but the daily-use experience is meaningfully better.

What's new

🎨 App icon — Finder, LaunchPad, Cmd+Tab, and Spotlight now show a proper red-record-dot squircle instead of the generic macOS app placeholder.
📊 Live level meters in the menu bar popover — one bar per channel, green → yellow → red. Confirms at a glance that audio is actually flowing, and makes muted channels visually obvious.
⏱️ Elapsed time in the menu bar — recording duration is shown directly next to the icon (e.g. 🔴 01:23), so you don't have to open the popover to check.
📖 README rewrite — leads with the product value, adds a comparison table vs Granola / Audio Hijack / BlackHole+OBS, collapses the architecture/internals into expandable sections, adds shields.io badges.
🛠️ TCC troubleshooting — documented the most common "permission silently denied after rebuild" gotcha, with a one-line tccutil reset fix.
🧰 Icon build pipeline — make-icon.py + make-icon.sh regenerate the icon from parameters. Changing colors / shape is now a one-commit edit.

Same as v0.1.0:

Drag MeetRec.app to /Applications
First launch: System Settings → Privacy & Security → Open Anyway, or:
```
xattr -dr com.apple.quarantine /Applications/MeetRec.app

If you only get mic audio after rebuilding, the Screen Recording TCC may be stuck:
