fix(server): preserve merged PR badges after branch deletion - #6216

💭 I want to check the changes made to GitManager.ts, so I'll look at that section of the file.

1. browse_code — apps/server/src/git/GitManager.ts

2. git_tools — readConfigValue

💭 I notice the whole check is wrapped so any failure in reading the config value defaults to false, which conservatively keeps the lookup — same safe fallback as before. I need to verify whether readConfigValue actually fails when the key is missing or just returns null, so I should check GitV's implementation.

3. browse_code — apps/server/src/vcs/GitVcsDriverCore.ts

💭 The allowNonZeroExit flag means a missing key just returns null rather than failing, which seems correct. The Effect.gen and orElseSucceed usage follows existing conventions without adding new imports or services, and the test file properly uses it.effect with a justified behavior-change test. I want to double check the imports in that test file next. Since I don't see any actual issues, I'm leaning toward reporting everything as clear, but I need to reconcile that with the required JSON output format — I'll structure the response as JSON indicating a clean result with a summary noting no findings.
