Implement the compiler configuration per MASTER_SPEC §23 in
compiler/common/config.py, with a strict configuration schema.
- Frozen dataclasses per section (analyzer, resolver, validator, prompt_builder,
debug) plus a top-level `schema` version; every default matches §23.2.
- Config.from_json validates against schemas/json/configuration.schema.json and
raises ConfigError carrying a Fatal SC0014 message on invalid input; every
section/field is optional and falls back to defaults.
- load_config(path) reads and validates a JSON file.
- Deterministic by construction: additionalProperties:false rejects unknown keys
(including any random seed); temperature has minimum 0.
- Injected into stages; no global/singleton config state.
- Ships config/default_config.json (the §23.2 example) as the canonical default.
Tests: defaults match §23.2, full/empty/partial load, file load, and
invalid-config rejection (wrong type, unknown field, forbidden seed, negative
temperature) producing SC0014.
