feat(runtime): implement console.table()

[nullptr-cve]

Summary

Implements console.table(tabularData, properties?) per the WHATWG console spec.

Behaviour

• Renders an ASCII box-drawing table with an (index) column plus one column per object property
• Arrays of primitives use a Values column
• The optional properties argument filters which columns are shown
• Falls back to console.log behaviour when tabularData is not an object
• Uses Object.keys() to enumerate only enumerable own properties (correctly excludes e.g. Array.prototype.length)

Example

console.table([{name: "Alice", age: 30}, {name: "Bob", age: 25}])

┌─────────┬───────┬─────┐
│ (index) │ name  │ age │
├─────────┼───────┼─────┤
│    0    │ Alice │ 30  │
│    1    │  Bob  │ 25  │
└─────────┴───────┴─────┘

Test plan

• console_table_array_of_primitives
• console_table_array_of_objects
• console_table_with_properties_filter
• console_table_non_object_fallback
