fix: use object schema for hooks.json to fix plugin load failure

[paikend]

Summary

• Four plugins shipped hooks.json as [] (empty JSON array) instead of {"hooks": {}} (empty JSON object)
• Claude Code validates hooks config against an object schema at load time, causing all four plugins to fail with: "expected object, received array"
• This prevented financial-analysis, equity-research, private-equity, and wealth-management plugins from loading on any OS (reported on Windows, but reproducible everywhere)

Root cause

The hooks.json files were initialized as empty arrays ([]) instead of the expected object structure. investment-banking was the only plugin with the correct format ({"hooks": {}}).

Claude Code's plugin loader runs schema validation (likely via Zod) that checks typeof data === 'object' && !Array.isArray(data). Since typeof [] === 'object' is true in JS but Array.isArray([]) is also true, the array fails the object check.

Fix

Changed 4 files from [] to {"hooks": {}}:

• financial-analysis/hooks/hooks.json
• equity-research/hooks/hooks.json
• private-equity/hooks/hooks.json
• wealth-management/hooks/hooks.json

Verification

// Simulated Claude Code validation
function validate(data) {
  if (typeof data !== 'object' || Array.isArray(data))
    throw new Error('expected object, received array');
}

validate([]);            // ❌ throws (BEFORE)
validate({"hooks": {}}); // ✅ passes (AFTER)

All 5 hooks.json files now pass object schema validation.

Test plan

• JSON syntax validation — all files parse as valid JSON
• Schema validation — all files are objects, not arrays
• investment-banking (already correct) — unchanged, still passes
