chore: update flake.lock to latest logos-cpp-sdk

[jimmy-claw]

Summary

• Updates logos-core-module/flake.lock to pull latest logos-cpp-sdk (95f763b → 1468180, 2026-04-13)
• Picks up SDK PRs: feat: A2A-spec HTTP/JSON-RPC server (#47) #48 (truly async method calls), feat: x402 payment middleware for A2A HTTP server #49 (async crash fix + regression test), feat: SDS Reliable Channel — bloom filter, lamport timestamps, causal ordering (#2) #31 (QVariantList/QVariantMap support), chore: remove LegacySdsTransport dead code #33 (IDL parser wip)
• logos-module-builder also updated (a86eea5 → 1247e5c, 2026-04-17)
• Several transitive deps restructured (logos-liblogos removed as direct dep, logos-plugin-core added)

Verification

• cargo build --all-features — pass
• cargo test --workspace — all tests pass
• No source code changes needed — IComponent API is unchanged
• Async call changes (feat: A2A-spec HTTP/JSON-RPC server (#47) #48/feat: x402 payment middleware for A2A HTTP server #49) don't affect LMAO's FFI layer (Rust-side async is independent)

Test plan

• cargo build --all-features succeeds
• cargo test --workspace — all pass
• nix build .#default in logos-core-module/ (requires nix with flakes)

Fixes #146

Re-verification (2026-04-19)

Re-ran full test suite to confirm stability:

• cargo build --all-features — pass ✅
• cargo test --workspace — 1060 tests passed, 0 failed ✅
• cargo clippy --workspace --all-features — clean (1 pre-existing collapsible_match warning in transport, unrelated) ✅
• No source changes needed — SDK update is binary-compatible

All checks green. Ready for merge.
