docs: DECISION-REGISTER entry 11 cycle is gone, and 14 verdicts are cut at ~900 bytes #10700

docs/DECISION-REGISTER.md has two defects, found while checking entry 11 after #10689.

1. Entry 11 describes a graph that no longer exists. It says {igla::coder::eval, igla::race::backend, igla::race::rtl} form one import cycle. On master ea39e99, eval.t27 and rtl.t27 import only base::types and math::constants. igla race: break the backend <-> rtl import cycle (Closes #10682) #10689 removed the last edge (rtl -> backend), and deps_cycles (t27f: list every spec on an import cycle (deps_cycles in spec_deps.t27) #10693) lists no spec on a cycle. The W608 and W614 comments the verdict cites are gone from both files.
2. Fourteen of the fifteen verdict paragraphs stop in mid-word, at 900 to 906 bytes (for example, entry 11 ends "...the transitive closure of imports g"). They were cut when commit 13b005f wrote them. git log --all -S finds the text in no other commit, so it cannot be restored.

Boundary

• In scope: a dated note in docs/DECISION-REGISTER.md that says which paragraphs are cut, and an update under entry 11 with today's graph.
• Out of scope: rewriting the cut verdicts, and any change to a spec.

User Scenarios

• A reader of entry 11 learns the cycle is gone and which PR removed it.
• A reader of any cut verdict knows the text stops early and does not finish the sentence from memory.

Requirements

• Every claim in the update names its source: a PR, an issue or a spec.
• No verdict text is changed or completed.

Success Criteria

• The note lists the measured cut lengths (900-906 bytes, 14 of 15) and the commit that cut them.
• Entry 11 carries an update that matches master's use lines.
