Bump SDK pin to 3.4.11; refresh vendored daml-props DAR

[peektism]

Summary

• All four daml.yaml manifests bumped: simple-token, simple-token-test, stablecoin, stablecoin-test → sdk-version: 3.4.11.
• Forward-looking docs updated to match: README.md, docs/SCOPE.md, docs/stablecoin/SCOPE.md, docs/PLAN.md (current state + version-pinning section), docs/stablecoin/PLAN.md (example daml.yaml blocks).
• dars/daml-props-0.1.0.dar rebuilt from daml-props at SDK 3.4.11.

Historical records intentionally left at 3.4.10

• docs/AUDIT.md, docs/stablecoin/AUDIT.md — audit results from the prior audit pass.
• docs/PLAN.md "Step 1 ✅ COMPLETE" — records the original creation at 3.4.10.

Coordinating PR

The rebuilt dars/daml-props-0.1.0.dar is from OpenZeppelin/daml-props#1. Merge this after that PR lands and a 3.4.11-built DAR has a stable upstream reference, or accept the DAR as-built for now.

Verification

Built and tested locally on 2026-05-18 with OpenJDK 21.0.11 / DPM SDK 3.4.11:

• simple-token dpm build — clean
• simple-token-test dpm test — 42/42 ok, 0 failures
• stablecoin dpm build — clean
• stablecoin-test dpm test — 27/27 ok, 0 failures

Test plan

• CI build passes for all four packages on 3.4.11
• CI test suites pass (simple-token 42/42, stablecoin 27/27)
• Vendored DAR consumed by simple-token-test and stablecoin-test matches what gets rebuilt from daml-props at HEAD
