* fix(policy): harden unknown-host DNS observations
- Emit the policy_dns_ineligible denial for every unknown name and
report observation staging failures as DNS failure events.
- Refuse unknown names during fail-closed quarantine and after the
observation budget, now a quarter of each address family's pool.
- Pin transparent TCP to the mapping of the deciding policy generation
so a reload between DNS and authorization fails closed.
- Stop Docker workloads from inheriting host DNS search domains, which
let the first expanded short name claim an observation address.
- Share mechanistic draft polling in conformance, register
new-hostname-proposal in the installed suite, and update docs.

* test(policy): build policy DNS proxy tests on every target
The proxy tests name PolicyEndpointId, which proxy.rs imported only on
Linux, so the macOS test build failed. Import it for test builds too.

* fix(policy): name DNS queries and mapped hosts in OCSF denials
DNS denial and failure events attached port 53 to the queried name,
which read as a connection to that host. They now carry only the name.
Transparent TCP denials for a policy DNS address show the mapped
hostname and keep the synthetic address in dst_endpoint.ip.
