teknium1 8cecaf0b29 feat(process): escalate SIGTERM->SIGKILL on host-pid termination after grace
A daemon that ignores or stalls in its SIGTERM handler currently survives the
process-registry reap and leaks until reboot (observed as agent-browser
daemons accumulating to EMFILE on long-running gateways). _terminate_host_pid
now snapshots the tree, SIGTERMs it, waits a bounded grace window
(terminal.daemon_term_grace_seconds, default 2.0s, 0 disables), then SIGKILLs
any survivor. The recycled-PID identity guard still gates the whole path, so
escalation never reaches a stranger; Windows is unchanged (taskkill /F is
already a hard kill).

Config lives in config.yaml (terminal.daemon_term_grace_seconds), NOT an env
var, per the .env-secrets-only policy.

Implements the SIGKILL-escalation idea from @tkwong's #15008, reworked onto the
current _terminate_host_pid tree-kill path (the original predated it) and
config-gated instead of env-var-gated.
