fix(hooks): correct hooks.json schema in three vertical plugins

[ali5996610-dot]

Summary

The hooks.json files for three plugins (equity-research, financial-analysis, private-equity) contain an empty array [] at the root, but the Claude Code plugin loader expects an object with a hooks key. All three plugins fail to load on install with:

Hook load failed: [
  {
    "expected": "object",
    "code": "invalid_type",
    "path": [],
    "message": "Invalid input: expected object, received array"
  }
]

This change updates the three files to match the format already used by the working investment-banking plugin: {"hooks": {}}.

What changed

• plugins/vertical-plugins/equity-research/hooks/hooks.json: [] → {"hooks": {}}
• plugins/vertical-plugins/financial-analysis/hooks/hooks.json: [] → {"hooks": {}}
• plugins/vertical-plugins/private-equity/hooks/hooks.json: [] → {"hooks": {}}

How to reproduce the bug

1. claude plugin marketplace add anthropics/financial-services-plugins
2. claude plugin install financial-analysis@financial-services-plugins
3. claude plugin list — plugin shows ✘ failed to load with the schema error above.

Test plan

• Install one of the affected plugins from this branch and confirm claude plugin list shows ✔ enabled.
• Confirm investment-banking (already passing) still loads without regression.
