chore: Greptile deep-label repo config (plan 028)

[zen-agents]

Adds .greptile/config.json at repo root (plan 028).

• Greptile only on label review:deep
• App authors included; non-implementation bots excluded
• triggerOnUpdates false; autoApprove off; statusCheck on
• commentTypes logic/syntax; ignore lockfiles/dist/.next/node_modules

Pilot canary agency-automations #70 green (exactly one Greptile on label-only dispatch).
This PR is labeled review:standard (CodeRabbit only) — config fan-out should not burn Greptile credits.

Summary by CodeRabbit

• Chores
  • Added project configuration to standardize automated review behavior.
