docs(adr): renumber the token/scope-tree ADR 0037 → 0039 (resolve collision)

ADR-0037 was claimed by two merged PRs: #1694 "Live Canvas" (created earlier,
2026-06-10) and #1706 "concurrent durable pause / token tree" (this work,
2026-06-11). Live Canvas has precedence, so the token-tree ADR yields to the
next free number (0038 is the Build Verification Loop). Renames the file to
0039 and updates only this work's own references — the ADR-0019/0031
forward-refs, the flow guide's Track A/B links, and the showcase flow comments.
The Live Canvas ADR stays 0037, untouched.
