Pull request overview
This PR adds safeguards to prevent performance issues in repo info telemetry caused by very old merge base commits. It introduces two main improvements: a configuration toggle to disable the telemetry and a 30-day age limit check for merge base commits.
Changes:
- Added a team-internal configuration setting
chat.advanced.debug.disableRepoInfoTelemetryto provide an emergency shutoff for repo info telemetry - Implemented a 30-day maximum age check for merge base commits before performing diff operations, preventing expensive git operations on stale branches
- Added new telemetry result type
mergeBaseTooOldto track when commits are rejected due to age

Context for this fix:
Our first party only repo info telemetry looks to create diffs between the public upstream and the current working tree of the local repo. It starts out by first doing a git diff to see just the names and counts of the files in the diff. Then, if it sees too many files, it exits early to avoid perf issues. We get this upstream branch for comparison by first looking for a set upstream tracking branch, and then if that fails using getMergeBase to get a comparison branch.
However in the case for some Windows devs, the tools they use to branch often don't set an upstream and the branch that they appear to have branched from is sometimes all the way back at the start of official/main. This is over four years old, and when git tries to just see the names and counts of files in the diff it churns up a huge git process causing performance issues.
This PR does two things.
