Make output_limit in runCommand configurable or increase it

[zendrx]

Problem

The runCommand function in src/Package.zig has a hardcoded output_limit of 1 MB (1024 * 1024). If a build command produces more than 1 MB of stdout or stderr, it crashes with error.StreamTooLong.

Steps to Reproduce

1. Run a build step that generates more than 1 MB of output
2. The command fails with error.StreamTooLong

Expected Behavior

• The limit should be configurable (e.g., via an environment variable like BUZZ_BUILD_OUTPUT_LIMIT)
• Or the limit should be increased to a more reasonable default (e.g., 16 MB)

Link to Code

buzz/src/Package.zig

Line 494 in e8dbd1c

const output_limit = 1024 * 1024;

Suggested Fix

const output_limit = std.process.getEnvVar("BUZZ_BUILD_OUTPUT_LIMIT") catch "16777216";
const limit = try std.fmt.parseInt(usize, output_limit, 10);
