chore(deps): russh-keys without OpenSSL; bot terse processing reply (#230)

- Remove workspace openssl; use russh-keys default (pure-Rust) crypto for ssh-remote
- Git2 on non-Windows still uses vendored-openssl for libgit2 only
- Bot chat: when verbose_mode is off, processing reply omits /cancel_task hint
