feat: support Python 3.14 and widen range to 3.11-3.14

Move the supported interpreter range to >=3.11,<3.15, dropping the EOL 3.10 floor and unblocking installs on 3.13/3.14.

- pyproject: requires-python ">=3.10,<3.13" -> ">=3.11,<3.15"
- update_checker: replace deprecated asyncio.get_event_loop() with asyncio.to_thread() (warns on 3.12+, slated for removal)
- test_compression: simplify _run() to plain asyncio.run()
- README: bump documented Python range to 3.11 - 3.14
- uv.lock: regenerate for the new interpreter floor
