Captain Code v0.3.4

Retract v0.3.0 to v0.3.2

v0.3.0, v0.3.1 and v0.3.2 can freeze the brain: the triage-shadow deadlock fixed in v0.3.3. Their tags and releases have been removed, and go.mod now retracts them, so go get warns anyone still on them and @latest never resolves to them.

The code is the same as v0.3.3; see its notes for the fix.

Install or update: go install github.com/lemma-ventures/captaincode/cmd/captaincode@latest.
