Remove the caption-as-alt fallback introduced in the PDF/UA compliance work (a867c3c, ba75b37). Using captions as alt text is an accessibility anti-pattern — captions describe a figure's significance in context while alt text describes what the image looks like. LaTeX: remove 3 caption-as-alt blocks in latex.lua, and add fig-alt to alt conversion in pandoc3_figure.lua for Pandoc 3 Figures without cross-ref labels. Typst: mark figure images with _quarto_no_caption_alt so that the caption-as-alt fallback in typst.lua only fires for inline images (where image.caption IS the standard markdown alt text). Key insight: In Pandoc 3, {alt="text"} replaces the Image's caption content rather than populating image.attributes["alt"]. So image.caption serves double duty as both visible caption and alt text override. We distinguish the two cases by comparing image.caption to figure.caption — when they match, the caption was NOT overridden (the bug case we suppress); when they differ, an explicit {alt="..."} was provided (which we preserve). This is the same heuristic Pandoc's own Markdown writer uses when round-tripping Figures. Explicit fig-alt (Quarto's dedicated attribute) flows through a completely separate path and always works unambiguously. Fixes #14107

- Fix regex in parse-error.ts to handle tagpdf line continuations when filenames are long (the warning wraps across multiple (tagpdf) lines) - Update warning message to recommend fig-alt instead of caption-as-alt - Add printsMessage check to caption-not-alt-ua test to verify the missing alt text warning is surfaced - Use labeled figure in caption-not-alt-ua test to avoid unrelated UA-2 structural nesting issue with unlabeled figures - Add ua2-unlabeled-figure-caption test documenting known LaTeX/tagpdf limitation where unlabeled captioned figures produce <Caption> directly under <Document> instead of inside a grouping element

The update-test-timing.yml and daily test-smokes.yml schedule runs pass `buckets: ""` (all tests), but rsvg-convert and verapdf were only installed when `buckets` contained specific bucket names. This caused 4 pdf-standard/ua-* tests to fail every run since Jan 26. Use the same `format('{0}', inputs.buckets) == ''` pattern already used elsewhere in this workflow to detect all-tests mode. Fixes weekly timing update failures and daily schedule failures.

* Fix `quarto preview subdir/file.qmd` crashing with doubled path `quarto preview subdir/page.qmd` in a website project crashes with `readfile subdir\subdir\page.qmd`. The `projectPath` function was designed for output filenames (resolving relative to source directory via dirname+join), but was also called with the source path itself. When that source path was relative, dirname+join doubled the subdirectory. Split into two functions: `projectRelativeInput` for source paths (normalizes directly) and `projectOutputPath` for output filenames (preserves the dirname+join logic). * Add missing test for relative/absolute path cache convergence The FileInformationCacheMap (added in #13955) normalizes keys so that relative and absolute paths to the same file share one cache entry. This adds the test case that was missing from the original test suite.

* plan generation * parse and test new recipients field * delete claude files * support write_yaml_metadata_block as a path for passing recipients * compress into fewer separate test files * update changelog. I can push this to 1.10 if we don't want to rush here. * rename test * set email version in tests * parse emails with simplified regex (and add specific plaintext tests)
