fix(sliceAnsi): rewrite to match upstream slice-ansi behavior

Major rewrite of Bun.sliceAnsi to match the upstream slice-ansi npm
package behavior. Key changes:

- SGR style tracking: decompose multi-parameter SGR codes into individual
  fragments with proper open/close code mapping (Map<endCode, openCode>)
- Always emit close codes at slice boundaries for active styles
- Hyperlink tracking: properly track OSC 8 hyperlink open/close state,
  emit close sequences at slice boundaries
- Cross-ANSI grapheme clusters: strip ANSI codes first, then apply
  grapheme segmentation to visible characters, then map back
- Handle CR+LF as single grapheme cluster (GB3 rule)
- Treat non-SGR CSI, DCS, SOS, PM, APC as invisible control codes
- Support C1 control characters (0x9B CSI, 0x9D OSC, 0x9C ST, etc.)
- Match upstream width calculation: graphemes with fullwidth codepoints
  get width 2, regional indicators get width 2, default width 1

Tests ported from upstream slice-ansi test suite (130 tests, 1646 assertions).
