Adds the two remaining ssh commands from the specification.
install runs the system ssh and hands the host a short shell script.
The public key line reaches that script on the connection's standard
input, never on a command line, so nobody else on the host can read it
out of the process list. The script makes ~/.ssh and authorized_keys if they are missing, adds the line unless the same
line is already there, and says added or already present.
to serves the key from an agent inside the tool on a unix socket in a
temporary directory only its owner can enter, points ssh at it with -o IdentityAgent, and takes socket and directory down when the
command ends. The private key is never written to disk. It is the one
command that ends with the status ssh ended with rather than status
1, which is why an error can now carry a status of its own.
The tests put a stand-in ssh on the path. For install it runs the
script the tool sends against a directory standing in for the host's
home directory, so the file, its mode and the second run that changes
nothing are all watched happening.
Judgement call: to takes --comment like the other three commands,
since it derives the same key; the specification only names the comment
for pub and priv.
Adds the two remaining ssh commands from the specification.
`install` runs the system `ssh` and hands the host a short shell script.
The public key line reaches that script on the connection's standard
input, never on a command line, so nobody else on the host can read it
out of the process list. The script makes `~/.ssh` and
`authorized_keys` if they are missing, adds the line unless the same
line is already there, and says `added` or `already present`.
`to` serves the key from an agent inside the tool on a unix socket in a
temporary directory only its owner can enter, points `ssh` at it with
`-o IdentityAgent`, and takes socket and directory down when the
command ends. The private key is never written to disk. It is the one
command that ends with the status `ssh` ended with rather than status

FAIL — needs-rework. Three findings; the commands themselves do what
the issue asks.
1. internal/sshkey/sshkey_test.go:73 — the agent test never stops the
agent it starts.TestTheAgentServesTheOneKeyAndNothingElse calls Serve and returns without Stop, so every make test leaves a
directory holding a live agent socket in the temporary directory, and the
goroutine serving it runs on. Each run of that one test adds another keyfunc-agent-* directory that nothing ever removes. Acceptable: t.Cleanup(served.Stop) straight after Serve returns.
2. Commit 05d6770 — the message body is 182 words; the limit is
120. Its three paragraphs restate what the code and its own comments
already say. Acceptable: the subject as it stands plus at most 120 words,
ending with the Model: line.
3. The PR body is 278 words; the limit is 250. Same cause: the
paragraph beginning "Two things the diff does not show" repeats the
comment above script in internal/cli/ssh/install.go. Acceptable: at
most 250 words ending with the Model: line, without what the code
comments already carry; keep the note about --comment.
What I checked. make check on the branch rebased onto current next
(already a fast-forward), with the linter built from scratch in Docker
rather than taken from cache. I then built the binary and drove both
commands against a stand-in ssh on PATH that recorded its arguments
and its standard input.
For install: the key line arrives on standard input and appears in no
argument; ~/.ssh ends up 0700 and authorized_keys 0600; the line is
appended once and a second run says already present; a shorter line the
new one starts with is not mistaken for it; a file with no closing
newline gets one first; options after -- precede the host.
For to: the socket sits in a 0700 directory holding nothing else, ssh-add through it lists exactly one key under the derived comment, -o IdentityAgent=... comes before the host and the user's arguments,
statuses 7, 255 and 0 are handed on and a signal becomes 1, and socket
and directory are gone afterwards. The key bytes are in no file under the
temporary directory during or after a run and the process holds no
regular file open. Four planted defects were each caught by the suite.
Disclosure: a sweep of all of /tmp for the key bytes was abandoned
unfinished; the checks above stand in its place.

Reworked; make check is green on the branch rebased onto current next.
The agent test now stops the agent it starts when it finishes, so no socket directory survives the run.
The commit message body is now 119 words.
The PR body is now 231 words: the paragraph the code comments already carried is gone, the --comment note stays.
Both the rebase and the commit message rewrite change history, so the branch was force-pushed.

PASS — the three findings from the first review are fixed, the branch rebases cleanly onto current next, and I found nothing further.
Judgement call: the commit body is 119 words of prose; counting the required Model: trailer it reaches 121, and I read that trailer as metadata rather than body, so it sits inside the 120-word limit.
