v1.0: HTML dashboard SVG charts, author/license headers, final polish

HTML Dashboard (HtmlReporter):
- SVG timeline chart: inline polyline of last 50 SCI values with area
  fill, grid lines, Y-axis min/max labels, X-axis timestamps
- Per-script SVG sparklines: inline 120x24 polyline per script group
- Last vs Previous comparison column with percentage delta and color
  coding (green ▼ improved, red ▲ worse, gray ═ stable)
- All SVG generated server-side in PHP — zero external JS dependencies

Author/License/Version headers:
- Added @author fullo <https://github.com/fullo>, @license MIT,
  @Version 1.0 to all 17 PHP source files

Documentation:
- Updated doc/reporters.md with SVG timeline, sparkline, and
  last-vs-prev feature descriptions
- README test count updated to 119 tests, 569 assertions

Phar rebuilt (79.5 KB, 18 files).
119 tests, 569 assertions, PHPStan clean, 97% line coverage.

 ### What it shows
 
 - **Summary cards**: total requests, average SCI, total emissions, average response time
-- **Detail table**: timestamp, method, URI, response time, SCI score, peak memory for the last 200 requests
+- **SVG timeline chart**: inline SVG polyline of SCI values over the last 50 entries, with area fill, grid lines, and axis labels — no JavaScript required
+- **Per-script summary table**: grouped by script filename, with inline SVG sparkline, "last vs previous" comparison (with percentage delta), and first-half/second-half trend indicator
+- **Measurement parameters**: device power (E), grid carbon intensity (I), embodied carbon (M), device lifetime
+- **Detail table**: timestamp, method, URI (with script filename), response time, SCI score with delta marks (▲/▼), status badges (200/301/500), peak memory — last 200 requests
