   Remove deprecated strong-mode analyzer options

   • BREAKING: SDK constraint bumped to >=3.0.0 <4.0.0
   • Replace lint with flutter_lints: ^5.0.0
   • Remove deprecated strong-mode analyzer options
   • Migrate CI from Travis to GitHub Actions (ci.yml + web-demo.yml)
   • Add .mise.toml (Flutter 3.35.7) and .pubignore to version control

   Bug fixes:

   • Fix division by zero in normalizeValue when minValue == maxValue
   • Fix shouldRepaint only checking value — now compares full style equality
   • Fix null dereference on IconTheme.size (fallback to 24.0)
   • Fix threshold comparison: bars now active when value >= threshold (was >)
   • Add clamping in normalizeValue to 0.0–1.0 range
   • Fix user-provided levels silently discarded when count != barCount
   • Move clipRect outside loop in sector painter
   • Fix variable shadowing (offset → roundedOffset) in sector painter
   • Remove redundant imports (widgets.dart, cupertino.dart)
   • Update constructors to super.key / super parameter style

   Tests:

   • Fix sector test group label ('Bar' → 'Sector')
   • Remove unused bar_fixture import in sector tests
   • Delete orphan test/goldens/bars-threshold.png
   • Add test/util_test.dart and test/style_test.dart (12 unit tests)
   • Regenerate all golden files

   Docs:

   • Update README: new badges, requirements section, full parameter table,
     expanded usage examples with levels, custom ranges, and styling options
   • Update CHANGELOG with v0.5.0 entry
