fix: disinto up silently destroys profile-gated services (#845)

TOML-driven agent services (emitted by `_generate_local_model_services`
for every `[agents.X]` entry) carried `profiles: ["agents-<name>"]`.
With `docker compose up -d --remove-orphans` and no `COMPOSE_PROFILES`
set, compose treated the hired agent container as an orphan and removed
it on every subsequent `disinto up` — silently killing dev-qwen and any
other TOML-declared local-model agent.

The profile gate was vestigial: the `[agents.X]` TOML entry is already
the activation gate — its presence is what drives emission of the
service block in the first place (#846). Drop the profile from emitted
services so they land in the default profile and survive `disinto up`.

Also update the "To start the agent, run" hint in `hire-an-agent` from
`docker compose --profile … up -d …` to `disinto up`, matching the new
activation model.
