fix(config): validate parsed TOML against ConfigSchema at runtime

Amolith and Shelley created 2 months ago

Export ConfigSchema and PartialConfigSchema from schema.ts.
Use TypeBox Value.Check/Value.Errors in loader.ts to validate
parsed TOML before merging with defaults, and validate the
merged result against the full schema. Invalid config now throws
ConfigError with path, expected type, and actual value for each
violation.

Closes review issue #3.
