[BUG] LocalSessionManager polls git status every 10s on non-git directories, generating 6000+ errors

Description

LocalSessionManager repeatedly runs git status on directories that are not git repositories, producing thousands of identical error log entries. In this log bundle spanning ~18 days, 6,175 identical errors were recorded.

Environment

• OS: Windows 11 Pro 10.0.26100
• Claude Desktop: v1.1.4173
• SDK: v2.1.51

Error Message (repeated 6,175 times)

[error] [LocalSessionManager] Failed to check git status: git exited with code 128:
fatal: not a git repository (or any of the parent directories): .git

The polling interval appears to be ~10 seconds, running continuously for every active session regardless of whether the working directory is a git repo.

Additional Related Errors

On one occasion (2026-02-24), the repeated git spawning combined with memory pressure caused:

• git exited with code 1: error launching git: The paging file is too small for this operation to complete.
• git exited with code 3221225794 (STATUS_DLL_INIT_FAILED — git.exe couldn't load its DLLs)

Expected Behavior

• LocalSessionManager should check once whether a directory is a git repository before starting the polling loop
• If not a git repo, skip the git status check entirely
• At minimum, suppress repeated identical errors after the first failure

Impact

• Pollutes logs, making real errors hard to find
• Wastes CPU/memory by spawning git processes every 10 seconds
• Under memory pressure, the repeated spawning contributed to system instability
