- typescript ^6.0.2 → ^5.7.0 (eslint 9 compat)
- eslint ^10.1 → ^9.0 (match typescript-eslint 8.x)
- Regenerate package-lock.json

Rust crate (packages/agent-mesh/sdks/rust/agentmesh):
- rand 0.10 → 0.8 (OsRng moved, thread_rng removed in 0.10)
- sha2 0.11 → 0.10 (ed25519-dalek 2.x compat)
- thiserror 2 → 1 (stable API)
