Fix clone_repo TypeError and uvicorn reload loop triggered by data/repos writes

[Copilot]

Two bugs combined to crash the server during initialization: clone_repo() always raised TypeError due to a malformed tuple literal, and uvicorn's --reload-exclude pattern was too shallow to suppress WatchFiles events from deeply nested cloned repo files.

github_service.py — enumerate((1)) → enumerate([100, 1])

(1) is just the integer 1 in Python — no tuple is created without a trailing comma. This caused TypeError: 'int' object is not iterable on every new clone attempt, making it impossible to clone any repo.

The fix restores the intended fallback strategy:

# Before — crashes immediately
for attempt, depth in enumerate((1)):

# After — tries depth=100 first, falls back to depth=1 on index-pack/fetch-pack errors
for attempt, depth in enumerate([100, 1]):

run_commands.txt — data/* → data/**

data/* only excludes one level of depth. Files like data/repos/some-repo/backend/main.py were not matched, so every git clone into data/repos/ triggered a WatchFiles reload, interrupting initialization mid-run.

-uvicorn main:app --reload --port 8006 --reload-exclude "data/*"
+uvicorn main:app --reload --port 8006 --reload-exclude "data/**"

Pull request overview

Fixes two startup-breaking issues in the backend: a TypeError in repo cloning due to an invalid iterable, and a uvicorn reload loop caused by insufficient reload-exclude coverage for nested data/ paths.

Changes:

• Fix clone_repo() retry loop to iterate over intended depths (100 then 1) instead of crashing on enumerate((1)).
• Update dev run command to exclude all nested data/ paths from uvicorn reload triggers (data/**).
