Fix hooks/hooks.json schema in 4 plugins (record vs array)

[morganmaiani-bit]

Summary

Four of the five plugins in this repo ship hooks/hooks.json as [] (a JSON array). The Claude Code plugin loader requires {"hooks": {...}} and rejects the load via /doctor with expected: "record", path: ["hooks"], received: undefined. The fifth plugin, investment-banking, already ships the correct shape — this PR brings the others into line.

Plugin	Before	After
equity-research	[]	{"hooks": {}}
financial-analysis	[]	{"hooks": {}}
wealth-management	[]	{"hooks": {}}
private-equity	[]	{"hooks": {}}
investment-banking	{"hooks": {}}	unchanged

None of the five plugin.json manifests declare hooks, so this is a no-op functionally — it's purely a schema fix to silence the loader error.

Why this shape

investment-banking/hooks/hooks.json already passes the loader, so its content ({"hooks": {}}) is the safest target. An alternative would be to delete the hooks/ directory entirely on the four plugins, but that's a bigger diff and depends on loader behavior when the directory is absent. Minimum-diff wins here.

Reproduction

1. Add this marketplace via directory source in Claude Code.
2. Enable any of the four affected plugins.
3. Run /doctor. Observe:

Plugin (equity-research @ equity-research@financial-services-plugins): Hook load failed: [
  {
    "expected": "record",
    "code": "invalid_type",
    "path": ["hooks"],
    "message": "Invalid input: expected record, received undefined"
  }
]

After this PR, /doctor reports no errors for these plugins.

Test plan

• /doctor passes for equity-research, financial-analysis, wealth-management, private-equity after merge
• No regression for investment-banking (file unchanged)
• No regression in any plugin's actual command/skill/hook behavior (no hooks are declared in any plugin.json)

Thanks for catching this and taking the time to send a fix! 🙏 This was reported by many contributors — the underlying bug is now resolved in #232, which repairs all four broken hooks.json files ([] → {"hooks": {}}) and adds a plugin-validate CI check (the official claude plugin validate) so a malformed manifest can't regress again. Closing as superseded by #232. Really appreciate the contribution.
