Add agent-orchestration skill (Pavilion 201 giveaway)

[scott-wueschinski-GTMify]

Adds the agent-orchestration skill, the giveaway extension for Pavilion AI in GTM School 201 Class #6 (Advanced Agents: Autonomous GTM Systems).

What this adds

• skills/agent-orchestration/ with SKILL.md + COWORK-PROMPT.md + README.md, matching the convention of the other 62 skills.
• Teaches chaining existing aigtm skills into one supervised, semi-autonomous GTM motion mapped to the five-layer Autonomous GTM Stack (Trigger, Agent, Execution, Human-in-the-loop gate, Feedback), with a mandatory human gate before any customer-facing action.
• Worked example chains real skills already in the repo: prospect-research to cold-email to [gate] to post-call-summary to win-loss-analyzer.
• README gains an "Agents and orchestration (201)" section pointing at the skill and the /autonomous-gtm companion page.

Install-clean (no secrets or endpoints). Holds the house no-dash style.
