Closes #1805

Overview

Adds a few guards to prevent regressions during chunking refactor. These guards cover stale numba caches via inline="always", and possible regressions if using fastmath in accuracy-sensitive code regions.

These cover H1 and H2 of #1789

CI clears numba cache

Guard numba flags the compensated EFT kernels depend on

Add a test that forbids fastmath anywhere code from uxarray.utils.computing
is compiled, and requires error_model="numpy" on acc_sqrt_re, _accux_gca,
_accux_constlat and every kernel they are inlined into. An inline="always"
callee is compiled with its caller's flags, so the test follows numba's
inline call chains rather than only checking the definitions.
