Feat/more schemas injected

[mathpirate]

Adds injected schemas for a variety of CT types, eg Cell.of, Cell.for (and the equivalents for other Cell-like types), cell (the constructor), and generateObject

Test plan still only partially implemented but basics seem like they are working

Type narrowing for literal values is hacky and needs improving in a future follow-up

Summary by cubic

Automatically injects JSON schemas into Cell constructors and factory methods, and adds literal type widening to produce simpler, more general schemas. Also fixes link resolution to drop schemas when a remaining path field is not defined.

• New Features

  • Injects schemas for cell(), Cell.of(), OpaqueCell.of(), Stream.of(), ComparableCell.of(), ReadonlyCell.of(), WriteonlyCell.of().
  • Wraps Cell.for(...) with .asSchema(...) to attach schemas.
  • Supports wish() (schema as second arg) and generateObject() (schema in options).
  • Adds literal widening (number/string/boolean/bigint → base types), applies within arrays and nested objects, and merges identical schemas to reduce anyOf noise.

• Bug Fixes

  • Cell.of() with no value now inserts undefined as the first arg so the schema stays in the second position.
  • Link resolution removes schema when following a path to a field not present in the schema (no parent schema leakage).
