fix(ox-hugo): serve gitignored content and static assets, fix figure shortcode order

- glob.ts: add optional respectGitignore param (default true) so callers
  can opt out of gitignore filtering for generated directories
- build.ts: pass respectGitignore=false when globbing content/ so
  gitignored-but-generated markdown files are always picked up
- static.ts: copy top-level static/ → output/ root with gitignore disabled,
  mirroring Hugo's convention so ox-hugo images at static/ox-hugo/* are
  served at /ox-hugo/* as expected by the exported markdown src paths
- oxhugofm.ts: run replaceFigureWithMdImg before removeHugoShortcode so the
  precise figure regex sees the intact shortcode before the generic {{.*}}
  stripper destroys it; also upgrade figureTagRegex to figureShortcodeRegex
  which matches the full shortcode form ox-hugo actually emits
