Add a post-parse a11y analysis pass that checks template ASTs for common accessibility violations and emits warnings. Integrated into the compile() pipeline — warnings are returned in CompileResult.a11y. 10 rules implemented: - img-alt: <img> must have alt attribute - click-keyboard: non-interactive elements with @click need keyboard support - anchor-content: <a> must have content or aria-label - form-label: form elements need id/aria-label/aria-labelledby - no-distracting: <marquee>/<blink> are forbidden - heading-order: heading levels must not skip - aria-role: role values must be valid WAI-ARIA 1.2 - no-positive-tabindex: tabindex should not be positive - media-captions: <video>/<audio> should have <track> - anchor-valid: <a> should have href Configurable via CompileOptions.a11y (disable rules or turn off). 43 new tests covering all rules, edge cases, and integration.
