Updates the SDF WebGL addon to xterm.js upstream commit 08829c7. Requires exactly @xterm/xterm 6.1.0-beta.336; the matching pristine WebGL addon is 0.20.0-beta.329.

Includes upstream cancellation of pending texture-atlas warm-up work and immediate WebGL context release on disposal. Fixes SDF atlas clearing when glyphs occupy a later page while the first page is empty, allowing warm-up to restart and cancel its old queue correctly.

Validation: TypeScript build, production ESM and UMD bundles, changed-file lint, and Chromium WebGL integration tests (80 passed, 9 existing skips). Warm-up and context-release tests run with SDF both disabled and enabled. The SDF warm-up restart regression failed before the atlas-clear fix and passes afterward.
