Symmetric with the acquireLease change. Lets plugin-backed sandbox
providers reject a reusable lease whose stored agentId doesn't match
the current run's agent, forcing the host to acquire a fresh lease
instead of stomping the previous agent's workspace state.

Thread agentId into PluginEnvironmentAcquireLeaseParams + host call sites
so plugin-backed sandbox providers (e.g. paperclip-plugin-k8s) can scope
lease state per-agent without needing an SDK callback or DB lookup.
Add an optional agentId field to PluginEnvironmentAcquireLeaseParams and
thread it through the host's environment-runtime + run-orchestrator call
sites so plugin-backed sandbox providers can scope lease state (subdirs,
PVCs, etc.) per agent without an SDK callback or DB lookup.
The field is required-but-nullable on the internal EnvironmentDriverAcquireInput
(string | null) so every call site has to think about whether it has an
agent context. Ad-hoc operator probes (agent test-environment route)
pass null. The plugin RPC payload omits the field entirely when null,
keeping wire compatibility with older plugin worker SDKs.
