Why do we need the option to switch it off? Why not always have uniqueness?

The built-in [UUID] replacement collapses every UUID to one token, so a golden cannot tell two distinct UUIDs apart (raised in review of #6995). Add a UniqueUUID test.toml knob (default false) that, when set, makes the built-in UUID replacement honor the existing Distinct numbering: distinct UUIDs in an output become [UUID][0], [UUID][1], ... in order of first appearance. Existing tests are unaffected (default off); a test opts in with UniqueUUID = true. Co-authored-by: Isaac <no-reply@databricks.com>

Changes
Add opt-in UUID numbering through
UniqueUUID, defaulting tofalse, with unit tests and acceptance selftests. Existing goldens stay unchanged.Why
Keep the UUID replacement implementation separate from the golden updates. This is layer 2 after #7420: #7423 prepares affected tests, then #7021 removes the temporary option and enables numbering unconditionally.
Tests
go test ./libs/testdiff ./acceptance/internaland both UUID acceptance selftests passed on this layer.This PR was written by Isaac and revised with Codex.
