Configure model settings for commands, agents, and skills

Set explicit model preferences to optimize for speed vs capability:

- haiku: 11 commands, 2 agents (issue-worker, pr-fixer), 10 skills
  Fast execution for straightforward tasks

- sonnet: 4 commands (groom, improve, plan-issues, review-pr),
  1 agent (code-reviewer)
  Better judgment for analysis and review tasks

- opus: 2 commands (arch-refine-issue, arch-review-repo),
  1 agent (software-architect)
  Deep reasoning for architectural analysis
