Migrate driver-fs, driver-localstorage, and driver-excel to v4.0.0

[Copilot]

Migrates three drivers to DriverInterface v4.0 spec, bringing ecosystem compliance to 87.5% (7/8 drivers). Each driver now supports QueryAST-based queries and unified command execution while maintaining full backward compatibility.

Changes

@objectql/driver-fs

• Added executeQuery(ast: QueryAST) and executeCommand(command: Command) methods
• Implements FilterNode → legacy filter conversion via convertFilterNodeToLegacy()
• Version: 3.0.1 → 4.0.0
• Dependency: Added @objectstack/spec ^0.2.0
• Tests: +11 new tests (47 total, all passing)

@objectql/driver-localstorage

• Added executeQuery(ast: QueryAST) and executeCommand(command: Command) methods
• Implements FilterNode → legacy filter conversion via convertFilterNodeToLegacy()
• Version: 3.0.1 → 4.0.0
• Dependency: Added @objectstack/spec ^0.2.0
• Tests: +10 new tests (41 total, all passing)

@objectql/driver-excel

• Added executeQuery(ast: QueryAST) and executeCommand(command: Command) methods
• Implements FilterNode → legacy filter conversion via convertFilterNodeToLegacy()
• Version: 3.0.1 → 4.0.0
• Dependency: Added @objectstack/spec ^0.2.0
• Tests: +10 new tests (49 total, all passing)

Documentation

• Updated DRIVER_COMPLIANCE_MATRIX.md to reflect 87.5% compliance
• Marked fs, localstorage, and excel as fully compliant

Usage

// New QueryAST interface
const result = await driver.executeQuery({
  object: 'users',
  filters: {
    type: 'comparison',
    field: 'age',
    operator: '>',
    value: 25
  },
  sort: [{ field: 'name', order: 'asc' }],
  top: 10,
  skip: 0
});

// Unified command interface
const result = await driver.executeCommand({
  type: 'bulkCreate',
  object: 'users',
  records: [
    { name: 'Alice', age: 30 },
    { name: 'Bob', age: 25 }
  ]
});

Implementation Pattern

Each driver follows the established migration pattern:

• executeQuery() converts QueryAST to legacy query format, delegates to existing find()
• executeCommand() provides unified interface for create/update/delete/bulk operations
• convertFilterNodeToLegacy() handles AND/OR/comparison node conversion
• execute() throws descriptive error directing to executeCommand()

Impact

• 137 tests passing across all three drivers (100% pass rate)
• Zero breaking changes to existing APIs
• Drivers support both legacy Driver and new DriverInterface
• Only driver-redis remains for full ecosystem compliance
