K. Hodges fa97abf0c3 Implemented deterministic diff generation via a new file_writer stage.
What changed:

  - Added file_writer stage support in nightshift/config.py:93, nightshift/agents.py:446, and nightshift/pipeline.py:374.
  - Added file-block parsing and deterministic patch generation in nightshift/patches.py:65.
  - file_writer agents now return complete file blocks:

    ```file:relative/path.py
    <complete file content>
    ```
    NightShift reads current files and generates the unified diff itself.

  - Existing patch_validator, patch_normalizer, and patch_apply still run after that.
  - Switched tiny-lisp-nightshift/nightshift.yaml:51 to type: file_writer.
  - Updated tiny-lisp-nightshift/agents/implementer.md:1 to request file blocks instead of diffs.
  - Updated README, tutorial, config reference, and design doc.

  Also added tests for parsing file blocks, generating multi-file diffs, validating those diffs, and running a full file_writer -> normalize -> validate pipeline.

  Verification: python -m unittest discover -v passes, 101 tests.
