Add DEFAULT_AGENT_PROVIDER (.env-backed, default 'claude'): newly created agent
groups are created on this provider; existing groups are never touched. Applied
at a single chokepoint — ensureContainerConfig stamps a fresh config row with it
(INSERT OR IGNORE, so existing rows stay frozen). Resolution is unchanged
(session -> container_configs.provider -> 'claude'); per-group
`ncl groups config update --provider` still overrides.
- config: DEFAULT_AGENT_PROVIDER constant.
- chokepoint: ensureContainerConfig defaults an absent provider to it,
normalizing claude/casing to NULL/lowercase; every creation path
(channel-approval, register, init scripts, ncl groups create afterCreate)
inherits it without each having to remember.
- subagents (create_agent) inherit the parent's effective provider, not the
global, so a child never spawns on a runtime the parent can't reach.
- setup persists the operator's pick to .env and pre-selects the current default
in the picker so a re-run does not silently reset it.
