feat(evidence): discover missing Evidence links without transferring records (#8633)

* feat(evidence): discover missing Evidence links without transferring records

An agent could only learn that a retained record's source was absent by reading
complete records or by having a downstream analysis refuse. The summary said
nothing about links, and complete-record retention was easy to mistake for
source closure.

- Add detail: links to get_evidence_bundle and CLI inspect-evidence-bundle:
  paged link rows with retained or missing status and no record payloads, for
  selected records against the whole session or file.
- Add retained-closure traversal, the walk composed workflows require, reporting
  complete or incomplete. Direct reads make no closure claim.
- Count direct and missing direct links in the summary.

Fixes #8454

* fix(evidence): count a repeated Evidence link once in every delivery

The Evidence schema does not deduplicate evidence_links, so the summary counted
a repeated link twice while link rows and counts reported it once. Both now read
one helper for a record's distinct direct links.

* test(evidence): validate link delivery against the advertised schemas

The test never called tools/list, so neither the shared validator nor the MCP
client checked its replies against what each profile advertises. A schema that
rejected the links result could have passed. Fetch the advertised definition and
validate every request and reply against it.
