+deps(auth): move the whole better-auth family 1.7.1 → 1.7.2 in step, and return `@better-auth/scim` to the family's `^` range (#13715)
+
+`@objectstack/plugin-auth` declared `@better-auth/scim` at an EXACT `1.7.1`
+while the rest of the family sat on `^1.7.1`, and `pnpm-workspace.yaml`
+forced the same exact resolution. That hold was deliberate and dated (#3653
+ruling, 2026-08-27): at the time `^1.7.1` resolved scim to 1.7.2, whose
+`better-auth` / `@better-auth/core` peers are `^1.7.2`, while the installed
+family was still 1.7.1 — and the workspace overrides would have rewritten
+those peer ranges down and *silenced* the mismatch rather than satisfy it.
+That ruling named the remedy: float to 1.7.2+ "with the family moved in
+step, never a side effect of a lockfile refresh". This is that move.
+
+All eleven family members go to `^1.7.2` together — `better-auth`,
+`@better-auth/core`, `@better-auth/scim`, `@better-auth/oauth-provider`,
+`@better-auth/sso`, the five adapters and `@better-auth/telemetry` — in the
+workspace overrides and in `@objectstack/plugin-auth`'s own declared
+dependencies, which are what a downstream `npx create-objectstack` install
+actually resolves (the overrides do not ship). Measured after the move: npm
+`latest` is 1.7.2 for all eleven, the install resolves exactly one copy of
+each at 1.7.2, and `@better-auth/scim@1.7.2` keeps its `^1.7.2` peers on
+disk — satisfied by the installed pair rather than rewritten down.
+
+scim rejoins the family's `^` shape rather than taking a fresh exact pin: its
+two sibling standalone plugins (`oauth-provider`, `sso`) peer the family
+identically and carry `^`, and this entry is also the GHSA-j8v8-g9cx-5qf4
+floor, which has to be able to take the next patch. The two shapes were
+measured against each other and resolve identically today, so the choice is a
+durability one, not a resolution one.
+
+No source change: `better-call@1.4.0` and `@better-auth/utils@0.4.2` are
+still peered exactly as they were at 1.7.1, and `better-auth`'s stale
+optional `better-sqlite3@^12.0.0` peer is unchanged, so the scaffold's
+`peerDependencyRules` are untouched.
