Fleet task has invalid worker.role member selector

Error message

Fleet task {} has invalid worker.role member selector {selector:?}: {error}

What it means

Thrown by freeze_fleet_task_members when a legacy worker.role value is being resolved as a member selector (because an exact Fleet/roster is in play) and resolve_member_in_profiles errors on it. The code path preserves the historical 'role is a posture' contract but treats ambiguity as fatal when a roster is selected, wrapping the resolver error with the task id.

Solutions

1. Rename the value into a valid worker.agent_profile selector, or change worker.role to a valid posture label (e.g. consultant/advisory).
2. Fix the selector per the wrapped resolver error's concrete complaint.
3. Add a matching member profile for the intended role so resolution succeeds.
4. Update legacy configs to the member-selector scheme after the roster migration.

Example fix

// before
role = "senior-reviewer"
// after
agent_profile = "senior-reviewer" # or role = "consultant" for a posture

// Rust
const POSTURES: [&str; 2] = ["consultant", "advisory"];
if let Some(role) = task.worker.role.as_deref() {
    if !POSTURES.contains(&role) && resolve_member_in_profiles(&profiles, role).is_err() {
        eprintln!("role {role:?} is neither a posture nor a valid member selector");
    }
}

When it happens

Trigger: Freezing a task that sets worker.role to a non-posture string while an exact roster is required: resolve_member_in_profiles rejects the string's structure, e.g. role = "senior reviewer" with selector syntax the resolver cannot parse.

Common situations: Older configs using free-text role labels now interpreted as member selectors after the roster feature landed; role containing characters the selector grammar forbids; mixing role and member naming schemes after migration.
