Enrich CRM example metadata with full @objectstack/spec capabilities

[hotlong]

🎯 Goal

Maximize the CRM example's use of @objectstack/spec features so that the Console front-end can verify all platform capabilities end-to-end.

📦 What's Being Enhanced

All 8 Object Definitions (account, contact, opportunity, product, order, user, project_task, event):

Enhancement	Description
Object metadata	description, titleFormat, recordName
Field enrichments	required, searchable, unique, defaultValue, helpText, placeholder, group, readOnly
Field type diversity	text, textarea, richtext, email, url, number, currency, percent, date, datetime, boolean, select (with colors), multi-select, lookup (single/multiple)
list_views	2+ list views per object (All, Active/Filtered) with sort/filter
actions	Object-level actions (Send Email, Change Status, etc.) to exercise the Action Engine
form_layout	Sections-based form layout organizing fields into logical groups
New fields	30+ new fields across all objects (tags, avatar, linkedin, expected_revenue, shipping_address, etc.)

Config & Docs Updates:

• objectstack.config.ts — Updated seed data, new views leveraging new fields
• ROADMAP.md — Completion entry added

🔑 Key Principle

• Only use features actually supported by ObjectSchema.create() and Field.*() from @objectstack/spec/data
• Keep backward compatibility with existing seed data field names
• Run tests to ensure nothing breaks

The coding agent is now working on the PR. You'll receive a notification when it's ready for review. 🚀
