- runAppBinary registers SIGINT and SIGTERM after its build and recursion
checks and runChild forwards each signal to the app binary, then waits
for it to exit, so stopping summer serve frees the port (WR-08)
- newAppCmd keeps the inherited stdin, env and output, and a context
cancel sends SIGTERM with a 15-second appShutdownGrace before SIGKILL
- the child stays in summer's process group so the admin password
prompts can read the terminal
- helper-process tests cover SIGINT, SIGTERM and context cancel
- console introduction notes the signal forwarding
- delegateCommands() builds every delegate from one table of name,
description and common-flags hint; toolCommands appends it
- route:list, key:generate, admin:create and admin:reset-password are new
delegates; the child keeps summer's stdin, so the password prompts work
- migrate:rollback, queue:work and schedule:run lose their hand-written
flag copies: --plugin, --queue and --once now pass through verbatim
- the command list marks delegates with "(flags pass to the app binary)"
and the help command prints a Long text with the common flags
- console introduction, setup-and-maintenance and the root README
describe the passthrough behaviour and the new delegates
- delegateCommand builds a Passthrough bonfire command, so
`summer serve --addr :8123`, `summer serve --help` and `-h` reach the
app binary instead of failing with "unknown flag: --addr"
- one leading "--" is dropped so `summer serve -- --addr :8123` still
works
- appRunner is a package-level seam that tests replace to capture argv
