Bug: bunx opencode-ai installs incorrect musl binary on WSL (glibc environment)

Description

Hi team,

I'm encountering an issue when attempting to use the opencode command-line tool via bunx in a WSL (Windows Subsystem for Linux) environment.

Problem:
When I execute bunx opencode-ai in my WSL2 environment, Bun proceeds to download and run the tool. However, it appears to be selecting and installing opencode-linux-x64-baseline-musl in the temporary bunx cache. My WSL environment, however, uses glibc (as is typical for most WSL distributions). This results in runtime errors related to libc incompatibility when opencode-ai attempts to execute its underlying binary.

Specifically, the opencode binary (from node_modules/opencode-ai/bin/opencode within the bunx cache) fails to execute because it's compiled against musl while the system expects glibc.

Expected Behavior:
When bunx opencode-ai is executed, the opencode-ai package should correctly detect the glibc based WSL environment and ensure that the appropriate glibc compatible binary (i.e., opencode-linux-x64-baseline) is used/installed for execution.

Terminal Output:

$ bunx opencode-ai
ENOENT: no such file or directory, posix_spawn '/tmp/bunx-1000-opencode-ai@latest/node_modules/opencode-linux-x64-baseline-musl/bin/opencode'

$ ls /tmp/bunx-1000-opencode-ai@latest/node_modules
opencode-ai  opencode-linux-x64  opencode-linux-x64-baseline  opencode-linux-x64-baseline-musl  opencode-linux-x64-musl

$ /tmp/bunx-1000-opencode-ai@latest/node_modules/opencode-linux-x64-baseline-musl/bin/opencode --version
zsh: no such file or directory: /tmp/bunx-1000-opencode-ai@latest/node_modules/opencode-linux-x64-baseline-musl/bin/opencode

$ /tmp/bunx-1000-opencode-ai@latest/node_modules/opencode-linux-x64-baseline/bin/opencode --version
1.1.23

Feel free to ignore if this doesn't address your specific case.

Confirming that this also happens on native Linux. Since the automatic update to 1.1.25 on Ubuntu, it has been an issue:
