docs(changelog): lease timings measure pickup; model tables read providers by name

[indykish]

Adds a second Oct 13 changelog entry for the review fixes on agentsfleet #750. The merged entry from #215 stays as written, because the changelog voice keeps history append-only.

• First-token time — the run report's time_to_first_token_ms counts from the start of the run (agentsfleet 9ef061c2d). Setup time no longer counts, and the change needs agentsfleet-runner 0.60.0.
• Queue wait — queue_wait_ms is logged only for a newly read event, and clock skew reads as 0 (agentsfleet f08f3dfbf).
• Wrong secret field — the refusal names the fields the secret has, never their values (agentsfleet b0d9e2454).
• Model tables — providers sort by the name they show, badges are neutral, and the admin Model library ends at its rows (agentsfleet 7da9e39b3).

make lint passes. Merge this after agentsfleet #750 merges, since the entry describes that release.

🤖 Generated with Claude Code

Confidence Score: 5/5

The documentation change appears safe to merge after the product release described in the PR.

Summary

Adds an Oct 13 changelog entry covering:

• Run timing reports separate setup time from pickup time.
• Secret refusals name the fields a secret actually has.
• Model tables sort providers by their displayed names.

No actionable issues were found. The PR description from indykish intentionally keeps the earlier entry unchanged to preserve append-only history.
