Document exposed ports for reusable subcircuit interfaces

[rushabhcodes]

Summary

• explain how <port /> defines connection points in symbols and subcircuits
• show how connectsTo exposes an internal component pin
• demonstrate external connections with selectors such as FILTER.INPUT
• document direct-child port behavior with showAsSchematicBox
• cross-link the port and subcircuit references
• update the port props table with pinNumber, aliases, and connectsTo

Added in Port docs

Added in Subcirucit docs

Why

The existing port reference described ports as symbol-only and did not explain how to expose stable connection points from reusable subcircuits.

Validation

• bun run typecheck
• bun run build
• verified exposed subcircuit port behavior against the core regression test
