feat(supervisor): add flight10 (F10) program -- durable supervised launch

F10 (BLUE's kernel in the UV/VIOLET body, live-mainnet-capable, promotion-gated by
the arm file) now runs under supervisord as program flight10 instead of an ad-hoc
agent background task (which got reaped ~18min -- the only reason it kept dying).

Command SOURCES /root/flight10_prod.env (chmod 600, secrets NOT inlined here) so every
autorestart revive gets the full env (mainnet keys, DITA_V2_ZINC=REAL shared-RAM exec
plane, UV_EXEC_DARK_MODE=0, TP/SL, vol threshold, CH/HZ, arm-file path). Sets HOME + an
explicit PATH incl /root/.cargo/bin (the DITAv2 rust-backend provenance check shells
`rustc -vV`; supervisord's minimal PATH lacked it -> crash-loop). Clears stale
zinc_uv_exec_* regions pre-launch (RealZincPlane create=True FileExistsErrors on a
prior runner's un-reaped regions -> silent in-memory downgrade; F10 is sole owner so
clearing is safe -> REAL shared RAM every start/autorestart). Polite: startsecs=100 +
startretries=3 -> a startup-crash goes FATAL, never rate-loops BingX. autostart=false,
autorestart=true, log rotation, rlimit_as=3GB. BLUE (dolphin:nautilus_trader) untouched.
