Replace the writer spin lock with a blocking mutex
term_write_begin spun on an atomic sequence word. A waiter burned CPU,
and with no priority inheritance a SCHED_FIFO waiter could starve a
preempted holder on the same CPU. The writer section is now a pthread
mutex with PTHREAD_PRIO_INHERIT where the platform has it, and an SRWLOCK
on Windows. Re-entry on the owning thread still only counts the depth.
The platform wrapper (init, lock, unlock, destroy) is in compat.h. term_new
initializes the mutex, and term_free destroys it. Meson links the thread
library into the core, term_dep, and term_internal_dep. The README,
term.h, and the amalgamation note say that POSIX needs -pthread.
Tests: the feed and snapshot thread test now checks the final screen and
history against a serial reference. A new test checks that term_lock
nests and that another thread waits for the last term_unlock.
