Integrated SSH daemon authenticating against FSUTILS_PASSWD, with an ECDSA P-256 host key and an NSH session over a PTY per connection. Built from the upstream Dropbear tarball (pinned commit) and patched for NuttX, using Dropbear's bundled libtomcrypt for all crypto. setsid() (apache/nuttx#19184) and link() now come from NuttX, not local stubs.
