v0.144.3: drop unused local in mino_current_ctx to satisfy gcc

After v0.144.2 fixed the env/rest clobber warnings, gcc still
flagged the inline mino_current_ctx's local t when it expanded
into mino_bc_run's setjmp scope. The local was a single read
of mino_tls_ctx feeding a ternary; removing it makes the body
a direct conditional on the TLS variable, which silences the
false-positive warning. Generated code is unchanged on Apple
clang and gcc 12.

+## v0.144.3 — Build Fix: Drop Local In `mino_current_ctx`
+
+gcc's `-Werror=clobbered` flagged the local `t` in
+`mino_current_ctx`'s inlined body when the inline expansion
+landed in a function with a `setjmp`. The local was a single
+unused-after-assignment cache (`mino_thread_ctx_t *t =
+mino_tls_ctx;` followed by a ternary), so the warning was a
+false positive — but `-Werror` made it fatal anyway. Removed
+the local; the body is now a direct ternary on `mino_tls_ctx`.
+The compiler is free to load the TLS slot once; there is no
+observable change in generated code on either Apple clang or
+gcc 12.

 ## v0.144.2 — Build Fix: Mark setjmp-Adjacent Locals `volatile`
 
 GCC's `-Werror=clobbered` flagged three locals in `mino_bc_run`
