fix(team-skills): enable true parallel execution with --agent-name mechanism

Previously, parallel tasks assigned to the same role (e.g., multiple
EXPLORE-* tasks with owner: 'explorer') executed serially because only
one agent instance existed per role name. This adds conditional parallel
agent spawning with instance-specific names (explorer-1, explorer-2) and
--agent-name arg for role task discovery filtering.

Affected skills: team-ultra-analyze, team-quality-assurance,
team-brainstorm, team-issue. Single-task modes preserve backward
compatibility with original agent names.
