Ahoy's history store is a registry that holds no transcripts; build's history store is where a runner's transcript lands

A naming conflict (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/brief/04-surfaces/01-ahoy.md:427 — "the REGISTRY only: identity and lineage keyed on the root-commit SHA. ahoy owns it; it holds no transcripts"
• End B: .abcd/development/brief/04-surfaces/34-build.md:499 — "the runner's transcript lands in abcd's history store, keyed on the repository's root commit"

01-ahoy's user-scope inventory defines history/ as the registry only, keyed on the root-commit SHA, and says it holds no transcripts, with the transcript corpus kept in the sibling transcripts/< root-sha>/. 34-build says a runner's transcript lands in abcd's history store, keyed on the repository's root commit. So one name covers two stores: a reader of build cannot tell which directory a lane's transcript goes to, and a reader of ahoy is told the history store never holds one.
