test: port PR 6229 acceptance coverage to main

[AmyShang-alt]

What changed

Port the incremental acceptance coverage from PR #6229 onto the current main branch after its original stacked base branch was superseded by PR #6150.

• Add daemon process-restart reconciliation coverage.
• Add telemetry checkpoint/crash-window and ACP usage coverage.
• Add Anthropic BYOK URL normalization cases.
• Add service-error, AMR, packaged-updater, and Manual Edit E2E coverage.

Validation

• Targeted daemon reconciliation and telemetry tests passed.
• git diff --check passed.
• Typecheck was attempted; the current main workspace has pre-existing contracts/dist export mismatches unrelated to this port.

The coverage port itself is clear from the diff, but the PR body still needs a bit more review context before pool review picks it up. Could you add a short why section, a brief "what users will see" note (even if the answer is "no user-visible change; test coverage only"), and the surface-area checklist so it is obvious why these acceptance cases moved from #6229 onto main?

Found 2 non-blocking issues in the new manual-edit acceptance coverage that are worth tightening before relying on these cases as regression signal.

@AmyShang-alt I reviewed the changed ranges for the ported acceptance coverage across daemon restart reconciliation, telemetry/langfuse crash-window handling, AMR/service-error smoke flows, packaged updater floor routing, and the manual-edit history/clipboard cases. The assertions line up with the current implementation, and the earlier manual-edit follow-up fixes are present on this head. Nice job carrying this stack onto main cleanly.
