nix flake fails to build: bun version mismatch

[viitana]

Description

Hi, the opencode package defined in the repo's nix flake does not build. Seems like the project is relying on a bun version that is not available in nixpkgs.

❯ nix build github:anomalyco/opencode
error: Cannot build '/nix/store/wkzd5im19jzx7ppch1q7fdgmljzq4n3n-opencode-1.15.5+71e9007.drv'.
       Reason: builder failed with exit code 1.

This issue might be a duplicate of existing issues. Please check:

• Nix flake broken since 1.4.11 #23719: Nix flake build failures (broken since 1.4.11, similar build errors in the nix package)
• Opencode build fails in a nix flake input #18273: Opencode build fails when used as a nix flake input

If your issue is distinct (specifically the bun version mismatch with bun@^1.3.14 vs bun@1.3.13 in nixpkgs), please note that in the existing issues or add context to differentiate.
