Fix auth adapter runtime parity

🐛 Fixes ➖ N/A

🟢 95-100% confidence

Phase	🧪 Tests	🌐 Browser
Reproduced	🔴 Unbounded pagination, stalled-page termination, and action-safe typing failed before their owning fixes.	➖ N/A
Verified	🟢 31 focused tests, Convex 1.42 type regression, package build, and full bun check.	➖ N/A

✅ Outcome

Unbounded auth queries continue past 200 rows and abort pages that cannot make progress. Shared mutation contexts expose only the call shape valid from actions.

⚠️ Caveat

Browser proof is N/A for package runtime and type behavior. Fresh shadcn generation also advanced lucide-react from ^1.27.0 to ^1.28.0 in six generated fixture manifests; each targeted fixture check passes.

🏗️ Design

• Preserve the 200-row request cap while using an infinite total budget only when callers omit limit.
• Require every non-final page to advance its cursor or produce rows/count.
• Type RunMutationCtx.runMutation from GenericActionCtx.
• Run the committed type regression against pinned Convex 1.42.3 while regular package gates keep the supported Convex 1.38 baseline.

🧪 Verified

• bun test packages/kitcn/src/auth/adapter.test.ts packages/kitcn/src/server/context-utils.test.ts
• bunx vitest run packages/kitcn/src/server/context-utils.test-d.ts
• Production-revert type proof: fails with unused @ts-expect-error, then passes after restoring GenericActionCtx
• bun --cwd packages/kitcn typecheck
• bun --cwd packages/kitcn build
• Targeted scenario sync/check for next, next-auth, start, start-auth, vite, and vite-auth
• bun lint:fix
• bun check
• Final autoreview: TruffleHog clean; no accepted/actionable findings; patch correct at 0.91

Release the narrowed public context type as a minor

RunMutationCtx is publicly exported from kitcn/server, and this commit deliberately makes its third transactionLimits argument a type error, so existing consumers using that signature stop compiling. Classify this as a minor breaking change rather than a patch. .agents/rules/changeset.mdcL15-L19
