Per the 4-criteria decision rule (C1=cross-system, C3=tests, C4=size);
ProjectContext is the typed return of project_manager.flat_config();
the 5 sub-dataclasses model the actual nested dict structure of
flat_config()'s return; load_config_from_disk / save_config_to_disk
are the canonical config I/O primitives (renamed from the private
_load_config_from_disk / _save_config_to_disk).
This commit:
1. Creates src/project.py with ProjectContext + 5 sub (ProjectMeta,
ProjectOutput, ProjectFiles, ProjectScreenshots, ProjectDiscussion)
+ EMPTY_PROJECT_CONTEXT + _clean_nones + load_config_from_disk +
save_config_to_disk + parse_history_entries.
2. Removes the original class + function definitions from src/models.py.
3. Adds backward-compat re-exports in src/models.py (the same pattern
used by Phase 3a mma.py and Phase 3g personas.py).
4. Updates src/app_controller.py to use the new public function names
(load_config_from_disk / save_config_to_disk).
5. Updates tests/test_models_no_top_level_tomli_w.py to use the new
public name (the test still asserts lazy-loading; the lazy load
happens in the new project.py module).
6. Updates scripts/audit_no_models_config_io.py FORBIDDEN_PATTERNS to
reference the new public names (models.load_config_from_disk /
models.save_config_to_disk) + the new src.project path.

(re-exports work)
Pre-existing test regression (NOT caused by this commit):
tests/test_models_no_top_level_tomli_w.py::test_models_does_not_import_tomli_w_at_module_level
was already failing because the Phase 3g 'from src.personas import Persona'
re-export in src/models.py loads src.personas at module level, which
loads tomli_w. The Phase 5 reduce-models.py pass moves the persona
import into __getattr__ (lazy), which will make this test pass again.
