Add stop_process(name) following supervisor's stop rules: it always sets
manual_stop so the companion will not auto-restart. RUNNING/STARTING are sent
their stop_signal and moved to STOPPING with a stop_deadline (now +
stop_timeout) for the run loop to reap or SIGKILL; BACKOFF cancels its pending
retry and settles in STOPPED; STOPPED and STOPPING are success no-ops. Add
_signal_number to resolve a signal name and a stop_deadline field on
CompanionProcess.
Add tests for the running, backoff, already-stopped, unknown, and signal-name
cases.

Add start_process(name) following supervisor's start rules: STOPPED and
BACKOFF clear manual_stop, drop any pending retry, and spawn now; RUNNING and
STARTING report success without acting; STOPPING is rejected so the caller
retries. Returns (ok, message).
Add tests for the stopped, backoff, running, stopping, and unknown cases.

Reaping now transitions each exited companion via handle_exit: a manually
stopped one settles in STOPPED, any other exit enters BACKOFF with
next_retry_at = now + restart_delay (fixed, no exponential backoff or cap).
Add retry_backoff to re-fork BACKOFF companions once their delay elapses,
bumping restart_count and returning them to STARTING.
Add tests for backoff on unexpected exit, manual-stop staying stopped, retry
timing, and reap-to-backoff.

Add promote_running to CompanionManager: scans STARTING companions and moves
any that have stayed alive at least their startsecs window to RUNNING, logging
the pid and returning the promoted ones. Companions that die inside the window
are left to reaping.
Add tests for promotion after the window, too-early no-op, and non-STARTING.

Add reap_processes to CompanionManager: drains waitpid(WNOHANG), matches each
dead pid back to its companion, and records the exit via _record_exit (signal
number or exit code, exited_at, exit_count) while freeing the pid. Returns the
reaped companions; the restart decision stays with the run loop.
Add tests for exit-code, signal, and no-children cases.

Child calls _redirect_output after env setup: each configured log path is
opened append-mode and dup2'd onto fd 1/2. None/inherit keeps the inherited
fd; stderr stdout shares stdout's fd. Rotation stays external.
Add tests for inherit, append flags, file dup2, and stderr-to-stdout.

Strip whitespace also *after* header field value.
Simply refuse obsolete header folding (a default-off
option to revert is temporarily provided).
While we are at it, explicitly handle recently
introduced http error classes with intended status code.
