Omair Ahmed e8743e870b feat(tui): use OSC 8 hyperlinks in Markdown when terminal supports them (#3248) ...

TerminalCapabilities already tracks hyperlinks: boolean and returns true
for Ghostty, Kitty, WezTerm, and iTerm2, but nothing generated OSC 8
sequences. This completes that stub.

Changes to packages/tui:
- terminal-image.ts: add hyperlink(text, url) and setCapabilities()
- index.ts: export hyperlink and setCapabilities
- utils.ts: extend AnsiCodeTracker to track active OSC 8 URLs
  - process() now handles OSC 8 open/close sequences
  - getActiveCodes() re-emits the OSC 8 open at each line start
  - getLineEndReset() closes the OSC 8 hyperlink before each line break
  This ensures hyperlinks wrap correctly across multiple lines.
- components/markdown.ts: link renderer uses hyperlink() when
  getCapabilities().hyperlinks is true; falls back to (url) text
- Tests: new wrap-ansi tests for OSC 8 line-wrapping; terminal-image
  tests for hyperlink(); markdown tests covering both code paths;
  table-cell width test pinned to hyperlinks:false (checks raw columns)

closes #3239
