Docs only. Adds execution/p28-02/opt/: SPEC.md, TASK_INSTRUCTIONS.md and
registration/ (acceptance baseline of 12, registration and config
proposals, the before-derived fixed table of allowed cross-version
differences, and the byte-transfer record). Decision D1 is option B:
only the load_from_path failure path stops recording its performance
telemetry; the frozen E3 rule stays. The improvement rule is the formally
completed EQ SPEC §4. No product, frozen EQ or original-condition change;
23/88 and 4/30 unchanged. Registration is Root's; implementation is Opus.
