Clean up the agent socket and working files when a signal ends the tool (closes #17 )

check / check (push) Successful in 5s

Details

`cli.Main` ran the command tree on a background context, so SIGINT, SIGTERM or SIGHUP killed the process before deferred cleanup ran: `ssh to` left its agent socket and directory behind, and `ssh install` left a copy of the host's `authorized_keys` in its working directory. `Main` now runs the tree on a `signal.NotifyContext` for those signals; the cancelled context ends the child `ssh` or `sftp` and the cleanup runs. `ssh to` stops its child with SIGTERM, not a kill, so `ssh` restores the terminal. Exit status after a signal is 1 unless `ssh` reported its own.

The test re-runs the test binary as the tool, waits for the agent socket, sends each signal and checks the directory is gone.

Disclosure: the repeated `"uptime"` test literal became a `remoteCommand` constant because `goconst` required it.

Keep the mnemonic out of the ssh and sftp children (closes #16 )

check / check (push) Failing after 0s

Details

`keyfunc ssh to` and `keyfunc ssh install` started the system `ssh` and `sftp` with the tool's whole environment, so a mnemonic given in `KEYFUNC_MNEMONIC` stayed readable in the child's environment and could be forwarded to the host by a `SendEnv` line. Both children now get the environment with `KEYFUNC_MNEMONIC` and `KEYFUNC_MNEMONIC_COMMAND` removed, through one helper, `childEnv`, in the ssh cli package. The mnemonic command still runs with the full environment. Two tests drive the real commands against the stand-in `ssh` and `sftp` and check that a third variable still arrives.

The ssh install and ssh to commands (closes #2 )

check / check (push) Successful in 2m30s

Details

keyfunc ssh install appends the public line on a host through the system ssh, only when absent, feeding the line on standard input; keyfunc ssh to serves the derived key from an in-process agent on a private socket and runs the system ssh with it, the private key never on disk. Two review rounds; the second passed with no findings.
