fix(runtime): write wide chars at the terminal edge instead of clipping them (Ink parity) (#90 )

The paint Output write loop had two x-bounds guards Ink lacks, which dropped a whole wide
char -- including its in-bounds leading cell -- when only its trailing cell exceeded the
width, so an edge-aligned "aa你" rendered as "aa". Ink's Output write loop has no bounds
check: it writes both cells and lets the past-width placeholder be dropped as a sparse hole
by line.filter(undefined) + trimEnd. Removes the two guards to match (output.ts:272-308);
box-level overflow:hidden clipping is unchanged (the separate clipH sliceAnsi path).

Un-skips the non-hyperlink-OSC overflow-wrap test, which this also fixes (the now-visible
OSC bytes no longer push the trailing char off a clipped edge) -- verified "abcde\nfghij"
against the Ink reference. Adds a wide-char-at-edge test.

feat: test parity final push — 64 new tests, BSU/ESU, clear() API

Closes remaining test gaps between vue-tui and Ink:

Features:
- Add synchronized output (BSU/ESU) via DEC private mode 2026
- Add clear() API to TuiApp for erasing rendered output

Bug fixes:
- Cancel scheduler trailing timer on teardown (prevents stale commits)
- Guard teardown writes against ended/destroyed streams
- Reorder teardown to cancel timer before final commit

Tests (64 new, 2 skipped for known feature gaps):
- 7 BSU/ESU shouldSynchronize tests
- 5 borderBackgroundColor tests
- 13 component edge cases (empty text, number child, OSC hyperlink
  wrap-width, bare-text-in-Box validation, transform multi-line,
  leading whitespace, link escape closing)
- 13 text-width/CJK tests (alignment, truncation, overlay edge cases)
- 4 throttle + unmount edge cases
- 10 waitUntilRenderFlush write-callback-level tests + 1 clear() test
- 3 exit re-entrance tests
- 5 PTY #450 regression tests + 4 inline #450 tests

feat: rewrite Output class with StyledChar[][] grid for correct emoji/wide char handling

Port Ink's output character model using @alcalzone/ansi-tokenize. Each cell is now a
StyledChar with proper grapheme clustering. Fixes emoji alignment, wide char boundaries,
and changes clipping to top-only (matching Ink). Upgraded ansi-tokenize to ^0.3.0.
