fix(plugins): use canonical {"hooks": {}} for empty hooks.json

[devflowza]

Problem

Four vertical plugins ship hooks/hooks.json containing [] (an empty array). The Claude Code plugin loader's Zod schema expects an object at the root, so it rejects with:

Hook load failed: Invalid input: expected object, received array

Result: /doctor flags the plugin and the hooks can never be loaded.

Repro

/plugin marketplace add anthropics/financial-services
/plugin install financial-analysis
/doctor

→ ✘ Plugin errors → financial-analysis [financial-analysis]: Hook load failed: [{"expected":"object","code":"invalid_type","path":[],"message":"Invalid input: expected object, received array"}]

Fix

Change [] → {"hooks": {}}, matching the canonical shape already used by investment-banking/hooks/hooks.json elsewhere in this repo.

Affected files (4)

• plugins/vertical-plugins/financial-analysis/hooks/hooks.json ← actively erroring on /doctor
• plugins/vertical-plugins/private-equity/hooks/hooks.json ← latent (same bug, just not loaded by default)
• plugins/vertical-plugins/wealth-management/hooks/hooks.json ← latent
• plugins/vertical-plugins/equity-research/hooks/hooks.json ← latent

Verification

Patched the locally cached marketplace copies, ran /reload-plugins + /doctor — error cleared, all four plugins load cleanly.

Test plan

• /plugin install financial-analysis followed by /doctor shows no plugin errors
• Same for private-equity, wealth-management, equity-research

Hit this locally today after installing the marketplace. [] fails Claude Code's hook schema validation with Invalid input: expected object, received array on /reload-plugins. Patched equity-research/hooks/hooks.json locally and the plugin now loads cleanly — confirms the fix.

The {"hooks":{}} shape used in this PR also matches what investment-banking/hooks/hooks.json already uses upstream, so this keeps the corpus consistent. Cleaner than #192 (which uses the same shape but expanded across multiple lines).

[nmoralescyber]

Follow-up correction to my earlier comment: when I said "loads cleanly", I'd actually patched to bare {}. That only resolves the shallower top-level schema check. Re-running /reload-plugins against {} surfaced a second error:

{
  "expected": "record",
  "code": "invalid_type",
  "path": ["hooks"],
  "message": "Invalid input: expected record, received undefined"
}

Patching to {"hooks": {}} (the exact shape in this PR) does fully resolve it. So this PR's choice isn't just cosmetic alignment with investment-banking — the hooks key is required by the validator, not just an object root.
