Refactor formula engine and validator into separate plugin packages

[Copilot]

Extracted formula engine and validator from monolithic @objectql/core into dedicated plugins, improving modularity and bundle size with clean separation of concerns.

Changes

New Packages

• @objectql/plugin-formula - FormulaEngine and FormulaPlugin (573 LOC, 109 tests)
• @objectql/plugin-validator - Validator and ValidatorPlugin (744 LOC, 52 tests)

Core Package Updates

• Added dependencies on new plugins (for internal use)
• No re-exports - enforces explicit dependencies
• Updated internal imports (repository.ts, ai-agent.ts, plugin.ts)
• Removed 1,317 lines (moved to plugins)

Migration Path

Breaking Change: Applications must update imports to use dedicated packages:

// Before
import { FormulaEngine, Validator } from '@objectql/core';

// After
import { FormulaEngine } from '@objectql/plugin-formula';
import { Validator } from '@objectql/plugin-validator';

const kernel = new ObjectStackKernel([
  myApp,
  new FormulaPlugin({ enable_cache: false }),
  new ValidatorPlugin({ language: 'en' })
]);

Architecture

Before:

@objectql/core (monolithic)
├── Repository + Query
├── Formula Engine
└── Validator

After:

@objectql/plugin-formula (focused)
@objectql/plugin-validator (focused)
@objectql/core (lean, focused on core repository logic)

Follows existing pattern from @objectql/plugin-security. Enables tree-shaking and optional feature inclusion. Enforces clean architectural boundaries with explicit dependencies.

Testing

• All 282 tests passing (no regressions)
• CodeQL security scan: 0 alerts

Documentation

• MIGRATION_GUIDE.md with migration instructions
• Comprehensive READMEs for both plugins
• PLUGIN_REFACTORING_SUMMARY.md with metrics

Original prompt

公式引擎和validator是否建议分拆为单独的插件软件包。

不需要Re-exports components for backward compatibility @copilot

Done. Removed backward compatibility re-exports from @objectql/core. Users must now explicitly import from @objectql/plugin-formula and @objectql/plugin-validator. This enforces clean separation of concerns.

Updated documentation (MIGRATION_GUIDE.md and PLUGIN_REFACTORING_SUMMARY.md) to reflect this breaking change.

All 282 tests still passing. Commit: 73822a4

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• fastdl.mongodb.org
  • Triggering command: /usr/local/bin/node node ./postinstall.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
