Union of two parallel tracks. Both action rows, both menu rows, both link
edges survive; the two package CLAUDE.md files now describe the post-merge
reality rather than either side's pre-merge scope.
Delegates the refuse-gate to ledgerDegraded(), lifts its console message into a
pure testable fold, fixes stale doc line citations and an inaccurate outcome-enum
comment, and splits the rename counter into collision-vs-sanitize.
Clamps insertSuffix's underflow, floors uniqueEntryName's validity guard, suppresses
the redundant overwrite confirm via a picker out-param, adds a PayloadBuffer
high-water mark, and corrects stale CLAUDE.md/CMake claims.
REAPER's GetUserFileName serves both pickers — the no-save-picker finding was a
regex miss. A new enum value is structural, not additive: BankModel rejects an
out-of-range SourceMode/Tier rather than degrading.
