feat: add lead-intelligence skill, autonomous-agent-harness, and Gemini CLI target

New skills:
- lead-intelligence: AI-native lead intelligence pipeline with 4 agents
  (signal-scorer, mutual-mapper, enrichment-agent, outreach-drafter).
  Replaces Apollo/Clay with agent-powered signal scoring, mutual ranking,
  warm path discovery, and personalized outreach drafting.
- autonomous-agent-harness: Replaces standalone agent frameworks (Hermes,
  AutoGPT) using Claude Code native crons, dispatch, memory, and computer
  use. Documents the full architecture for persistent autonomous operation.

New CLI target:
- Gemini CLI: .gemini/GEMINI.md config added, gemini target registered
  in install-modules.json platform-configs module.

Updated:
- marketplace.json: Fixed stale counts (was "14+ agents, 56+ skills"),
  now accurately reflects 30 agents, 138 skills, 60 commands.
- README.md and AGENTS.md: Synced skill counts to 138.
- install-modules.json: Added lead-intelligence to business-content
  module, autonomous-agent-harness to agentic-patterns module.

All catalog validations pass (30/60/138). Install-manifest tests pass (20/20).

+2. **X API** — Recent tweets, bio, follower data
+3. **GitHub** — Open source profiles (if applicable)
+4. **Web** — Personal sites, company pages, press releases
+
