The $schema field in Claude Code settings no longer validates against the literal https://json.schemastore.org/claude-code-settings.json URL. It now accepts any string (or omission). This removes the hard dependency on that specific schema URL.
Evidence
Removed constant (search for "https://json.schemastore.org/claude-code-settings.json" — absent from v2.1.174)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
