Advance corpus to refreshed PR #104 and RSI artifacts

[luisleo526]

Advance the public corpus gitlink to pineforge-corpus PR #10 (d4bcabc).

The corpus milestone publishes deterministic artifacts for already-merged engine PR #104 and codegen PR #58:

• pyramid-cash-fractional-commission: Strong to Excellent;
• pyramid-deferred-flip-close-all: Strong to Excellent;
• ta-rsi-bb-self-bands: 350/351 Strong to 350/350 Excellent after regenerating stale C++ with the accepted float comparator;
• no tier downgrades.

Validation on this exact engine and corpus tree:

• 252/252 strategies ran successfully;
• verifier: 243 Excellent / 8 Strong / 1 Anomaly;
• validation report self-test: OK;
• six changed engine tapes reproduced byte-identically on a second targeted run;
• corpus PR chore(corpus): bump for lower-tf-03 message alignment #10 merge tree equals the locally tested head tree.

This engine PR changes only the corpus gitlink.
