skill: switch 40250 parity skill to file-by-file 1:1 porting

Unit of work is a 40250 source unit; current-only logic is a defect;
unreachable code is not evidence. Adds per-function port-map schema,
priority by player-visible gameplay, parallel worktree rules, and a
corrected project map.

+- Function keys are the reference's qualified names (`Class::Method`, or the free-function name).
+- `status` is one of `TODO`, `PORTED`, `ADAPTED`, `N_A`, `DIVERGENT`, `NEEDS_LIVE` (meanings in `SKILL.md`).
+- `impl` is required for `PORTED`/`ADAPTED`/`NEEDS_LIVE`; `note` is required for `ADAPTED`, `N_A`,
+  `DIVERGENT` and `NEEDS_LIVE`. `ADAPTED` also needs a `test` path.
+- When `reference_sha256` no longer matches the file, every non-`TODO` function in the unit must be
