fix(hooks): use object schema in hooks.json instead of empty array

[Halxan-dev]

Summary

• Replace [] with {"hooks": {}} in hooks.json for the four plugins that currently fail to load on Claude Code (Hook load failed: expected object, received array).
• Aligns with investment-banking/hooks/hooks.json, the only plugin in the marketplace that loads cleanly today.

Reproduction (pre-fix)

• Claude Code on macOS / Windows (verified on Windows 11, Claude Code current).
• claude plugin install <plugin>@financial-services-plugins
• claude plugin list reports failed to load for the four plugins, with:

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

Verification (post-fix)

• cat <plugin>/hooks/hooks.json returns the multi-line {"hooks": {}} form, identical to investment-banking.
• After reinstall, all five plugins should report enabled in claude plugin list (only the four touched by this PR were broken).
