Agent telemetry session validation

[ceylin-ece]

Summary

• Improve Goose and Codex session bootstrap and recovery for local studies.
• Update agent inference and tool handling used by the research proxy.
• Improve ACP telemetry normalization and tool-event correlation.
• Add a local study-seeding script and regression tests.

Verification

• Focused server tests: 47 passed.
• Tested Goose and Codex through local Code4Me studies and inspected saved telemetry.

Remaining work

• Some ACP events are still classified as unknown and need review.
• The corrected client plugin ZIP was not installed, so its stale-session fix has not been verified live.
• This is a draft for review, not a production-ready release.
