Sync Dependencies Hash

Update the fixed-output derivation hash in pkgs/bits-uberjar/default.nix after changing deps.edn.

Background

The uberjar build uses a fixed-output derivation (FOD) to cache Maven/Clojure dependencies. When deps.edn changes, the hash becomes stale and builds fail with a hash mismatch error containing the correct hash.

Process

1. Read pkgs/bits-uberjar/default.nix

2. Edit depsHash to an invalid value to force recomputation:

   depsHash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
   

3. Run: nix build .#bits-uberjar

   The build fails with a hash mismatch. Find the got: line containing the correct hash (format: sha256-...=).

4. Edit depsHash with the correct hash from the error output.

5. Verify: nix build .#bits-uberjar

6. If verification fails, restore: git checkout pkgs/bits-uberjar/default.nix
