rename officer-agent to officer-claude-code

The old name said nothing about what the process runs, and it sits directly
beside officer-anthropic-proxy — a different process doing a different job — so
"the agent" was ambiguous exactly where it mattered. CLAUDE.md already had to
spend a paragraph insisting the two are not the same thing. It spawns `claude`;
the name says so now.

Only two references were functional: the generator's CORE_PROCESSES and the CORE
list in catalogue.test.ts. Everything else was prose or comments.

Left alone deliberately: `x-officer-agent-token`. It looks like the same string
and is not — it is the agent-handoff HTTP header, naming a per-panel bearer
token, unrelated to any pm2 process. Renaming it would have changed a wire
protocol to tidy a label.

Historical docs keep the old name. claude-sidecar-isolation.md and
open-threads-after-per-user-claude.md are dated investigations that record the
PREVIOUS rename, from officer-claude to officer-agent, and rewriting them would
make that history unreadable. CLAUDE.md notes the change instead, where somebody
reading those will be looking.

Also worth recording, from the owner: merging this with officer-anthropic-proxy
into one sidecar was investigated tonight and rejected. They stay separate.
