feat(python): support Python 3.14

[pratyush618]

Adds Python 3.14 to the build, test, and publish matrices. pyo3 0.29 (shipped in 0.16.4) supports 3.14.

Verified locally on CPython 3.14.2

• maturin develop builds the cp314 extension against pyo3 0.29 — clean.
• 763 taskito tests pass on 3.14: core (314) + worker/workflows/resources/python/autoscale/observability (449). The single failure, test_prometheus_middleware_has_resource_metrics, is pre-existing on master (missing _init_metrics), unrelated to 3.14.
• Integration/dashboard suites not run locally — they pull third-party libs (flask/django/joserfc/boto3); their 3.14 readiness is the dependency's concern, not taskito's Rust↔Python ABI.

Changes

• publish.yml — --interpreter … 3.14 on all four wheel jobs (linux, musllinux, macOS, windows) + Set up Python 3.14 steps for the macOS/Windows jobs.
• ci.yml — 3.14 added to the ubuntu test matrix; macOS/Windows newest bumped 3.13 → 3.14.
• pyproject.toml — Programming Language :: Python :: 3.14 classifier (the PyPI pyversions badge picks this up on next publish).

Lands after 0.16.4 → first published in 0.16.5.

Summary by CodeRabbit

• New Features
  • Added Python 3.14 to the supported test matrix on Linux, macOS, and Windows.
  • Release artifacts now include wheels built for Python 3.14 (alongside 3.10–3.13).
• Chores
  • Updated the project’s metadata to advertise Python 3.14 support.
  • Updated CI build runners to newer macOS environments for release builds.

Poem

🐇 Hop, hop, the burrow's bright,
Python 3.14 joins the flight.
Wheels spin round and tests run true,
macOS gets a fresher view.
One node build hops to macOS 15,
The rabbit smiles: “All systems gleam!”
