1. 1. Summary

• Make hermetic GDB installation opt-in through the `install_gdb` Bazel setting; normal dist-test archives remain GDB-free by default.
• Add `install-gdb` and `archive-gdb` targets in `BUILD.bazel` for a separate Linux GDB sidecar archive.
• Add the Evergreen `archive_gdb` task and make `run_pretty_printer_tests` fetch and extract that sidecar explicitly.
• Keep directly targeted Bazel pretty-printer tests self-contained through runfiles in `pretty_printer_test_launcher.py.in`.
• Keep GDB configuration analysis tests small enough for repository-wide lint analysis.

This reduces the size of normal server archives while preserving the debugger files required by pretty-printer tests. The change is Linux-only and does not alter server binaries or the default archive contents.

1. 1. Validation status

Local validation passed:

• `bazel run lint //... --lint-yaml=mongodb-mongo-master --large-files` — all 23 checks passed.
• `bazel run format`
• Install-rule and pretty-printer tests — 5 passed.
• `bazel build --config=evg --config=opt_profiled //:archive-gdb`
• `git diff --check`
