Upgrade Python Deps
Automates the full cycle of upgrading Python dependencies with uv: locks to the latest compatible versions with a 7-day exclusion window for supply chain safety, syncs your environment, then runs mypy and your test suite to catch breakage. It's opinionated in a good way, stopping at the first failure and summarizing what changed before offering to commit. Most useful when you want to keep dependencies fresh without manually babysitting the upgrade-test-debug loop. The built-in guardrails around conflict resolution and the structured reporting of type errors make it less stressful than doing this by hand, though you'll still need to fix any actual breakage yourself.

Your task
Upgrade all Python dependencies and verify nothing is broken.
Step 1: Upgrade the lock file
Run uv lock --upgrade --exclude-newer "7 days" to upgrade all dependencies to their latest compatible
versions (with a 7-day cooldown to mitigate supply-chain attacks).
Review the output for any resolution errors. If there are conflicts, report them to the user and ask how to proceed before continuing.
Step 2: Remove the cooldown marker from the lock file
uv records the --exclude-newer cutoff inside uv.lock as project configuration. Since it
isn't declared in pyproject.toml, any later uv sync or uv run sees a config mismatch,
discards the lockfile, and silently re-resolves everything to the newest versions — undoing
the cooldown. Prevent this by deleting the [options] block at the top of uv.lock
(the exclude-newer / exclude-newer-span lines) before syncing:
sed -i '/^\[options\]$/,/^$/d' uv.lock
The cooldown-resolved versions stay in place; only the marker is removed. Verify with
grep exclude-newer uv.lock (should print nothing).
Step 3: Sync the environment
