Sydney RunkleandGitHub f95d2309f9 release(checkpoint-postgres): pin to checkpoint 4.1.0a1 (#7648 )

## Summary
- Bumps `langgraph-checkpoint-postgres`'s pin on `langgraph-checkpoint`
from `>=4.0.3,<5.0.0` to `>=4.1.0a1,<5.0.0` so the postgres alpha
(3.1.0a1) requires the matching checkpoint alpha released in #7647.
- Mirrors the same pin update applied to `langgraph` (1.2.0a1) on
`wfh/releases/timers`.

## Why
The three alphas (checkpoint 4.1.0a1, checkpoint-postgres 3.1.0a1,
langgraph 1.2.0a1) are meant to be tested as a coherent set. `langgraph`
already pins `>=4.1.0a1`; checkpoint-postgres was missed in that release
and is still letting resolvers fall back to 4.0.x.

## Test plan
- [ ] CI green
- [ ] `uv lock` resolves cleanly across libs (verified locally via `make
lock` — no lock file changes since editable paths already resolved to
4.1.0a1)
