chore: bump SDK version to 0.6.0

[koko1123]

Follow-up to #37: the version-bump commit raced the squash-merge and missed it. Aligns build.zig.zon .version with the v0.6.0 tag.

Note: the v0.6.0 tag will be moved to this commit once merged (created minutes ago, no consumers yet -- the gator-liquidators pin lands after this).
