fix(text): address PR #180 review

Follow-up cleanups on the merged TTF-fill work:

- Drop the unconditional resolve_text_style log line — it fired for every
  text style and spammed ~7k stderr lines opening a single real drawing.
- Drop the per-glyph tessellation-error eprintln; a malformed font would
  otherwise log once per character. The glyph still falls back silently.
- Tessellate glyph fills with the nonzero winding rule (lyon defaults to
  even-odd, which mis-fills TrueType outlines whose contours overlap).
- Make the sysfont prefix fallback deterministic (sorted) and require ≥3
  chars so a 1–2 letter request can't grab an arbitrary family.
- Remove the unrelated windows-gnu --exclude-all-symbols linker flag that
  slipped into .cargo/config.toml.
