End-to-end CLI surface for the personality overlay:
mcpctl create personality grumpy --agent reviewer --description "be terse"
mcpctl create prompt tone --agent reviewer --content "Be very terse."
mcpctl get personalities
mcpctl get personalities --agent reviewer
mcpctl edit personality <id>
mcpctl delete personality grumpy --agent reviewer
mcpctl chat reviewer --personality grumpy
Chat banner gains a "Personality:" line that shows either the active
flag value or the agent's `defaultPersonality` (when no flag given),
so the user knows which overlay is in effect before sending a message.
`--personality` is stripped from `/save` (it's a per-turn override,
not a `defaultParams` field — the agent's defaultPersonality lives on
its own column and is set via PUT /agents).
Backend (small additions to land Stage 4 cleanly):
- `GET /api/v1/personalities[?agent=name]` so `mcpctl get
personalities` doesn't require an agent filter.
- PersonalityService.listAll() aggregates across agents.
Completions: regenerated fish + bash. `personalities` added as a
canonical resource with `personality` alias; edit-resource list
extended; the per-resource argument completers pick up the new
type automatically.
CLI suite: 430/430. mcpd: 801/801. Typecheck clean.
