Shell discovery keyed entries by resolved path. On merged-/usr hosts the
login shell /bin/bash from $SHELL and the PATH hit /usr/bin/bash for the
`bash` candidate are one file with two spellings, so the menu showed
"bash" twice. Key discovered shells by executable name, compared without
letter case or `.exe`, and keep the earliest entry so the default shell
stays first.
Every Typert Remote stream accepts client-to-Host items on the same
logical stream. A method declares the uplink item type in its return
type, RemoteStream<Out, In>, and reads the items through
this.ctx.invocation.uplink(); the invocation also carries the calling
Peer. Client generated methods return a handle that iterates the
downlink and exposes send/end/dispose for the uplink.
