Pull Request Overview

Updates the project’s build setup to use Bazel 6 and brings related tooling declarations up to matching versions, while migrating Haskell test targets to the new ghcopts attribute and adding timeouts.

• Bump Bazel in shell.nix and pin a newer Nixpkgs commit in nixpkgs.nix
• Upgrade various http_archive and rule versions in WORKSPACE (rules_haskell, rules_nixpkgs, rules_go, gazelle)
• Rename compiler_flags → ghcopts across Haskell BUILD.bazel files, add timeout = "short" to tests, and update .bazelrc for Java 11

• Disabling experimental_strict_java_deps can have subtle effects on Java dependency resolution; please document the rationale for turning it off.

[nitpick] The comment # keep is ambiguous; consider clarifying its intent or removing it if it’s no longer needed.

bazel complains otherwise that "//jvm-batching:jar" is missing from the direct dependencies of "//jvm-types:jar" even though the dependency is listed there.
