land: catalog-trace-trust

[aft-alfonso]

Accepted agent delivery; branch-keyed search descriptor included.

---

Summary by cubic

Traces slow provider reads (e.g. tool.catalog) and retires the stale first-party trust id alfonso-core.

• Provider reads now record full phase timings through the existing slow-call log, with the session included in each trace line.
• Failed tool.catalog replies (write errors, route release, serialization/frame build failures) now emit warning logs with session and correlation data.
• The index census parser now accepts the new session= field in slow-call lines, with a regression test pinned to the CI cost-gate step.
• alfonso-core no longer resolves to first-party trust; it returns Untrusted like any other retired module id.
• Adds a benchmark slice descriptor for land/catalog-trace-trust.

^{Written for commit 3a582d4. Summary will update on new commits.}

Confidence Score: 5/5

The PR appears safe to merge; the follow-up fixes the earlier parser issue without introducing a new failure.

Summary

Adds session-tagged timing logs for provider reads, warning logs for failed catalog replies, and removes first-party trust for alfonso-core.

• Provider reads now show their timing and session in slow-call logs.
• The retired alfonso-core id no longer receives first-party trust.
• The slow-call census reads logs with or without a session field.
• The benchmark harness now has a descriptor for this catalog-trace slice.
