CI: Measure Numba JIT coverage in a single dedicated job (#913)

Remove the five Numba decorator patterns (@jit, @njit, @overload,
@guvectorize) from .coveragerc exclude_lines. coverage.py excludes the
entire decorated function when a decorator line matches, so ~1,700
statements of jitted code were invisible to coverage. Also omit the
test tree (*/tests/*) so the headline figure measures library code
only.

Since numba 0.61 (fixed to respect coverage configuration in 0.62), the
compiler emits coverage for JIT functions at compile time when
NUMBA_JIT_COVERAGE=1. Because emission happens during lowering, functions
with cache=True loaded from a warm on-disk cache report nothing, so the
coverage job points NUMBA_CACHE_DIR at a throwaway directory to force
compilation.

Restructure ci.yml accordingly:

- The OS x Python matrix now runs plain pytest (the production
  configuration, no coverage overhead).
- A new single `coverage` job (ubuntu, Python 3.13) runs the suite once
  with NUMBA_JIT_COVERAGE=1 and uploads to Coveralls. With one producer,
  the old per-matrix Coveralls gate is obsolete.
- Pin numba>=0.62 in environment.yml; without the env var taking effect
  the reported total would silently drop by ~5 pp.

New baseline: 90.55% (5,638 source statements, 533 missed), 600 tests
passing.

Closes #871
