removing automaxprocs

[itspooya]

Hi,
Previously I have created following pull request to fix an issue which was present on older golang versions
#1297
but golang v1.25 has added this feature and I think based on that, using a custom library is not needed anymore

I think previously @tariq1890 reviewed previous Pull request
If you could review this as well, it would be great

Thanks for the contribution @itspooya. Would you be able to rebase and resolve the merge conflicts?

I was able to confirm this is working as expected. Below is how I verified.

I added the below print statements to the top of main.go:

fmt.Println("GOMAXPROCS:", runtime.GOMAXPROCS(0))
fmt.Println("NumCPU:", runtime.NumCPU())

Before df18cd2 was introduced, the output was below:

GOMAXPROCS: 32
NumCPU: 32
{"level":"info","ts":1767744021.0677776,"msg":"version: v24.9.2, commit: b19241abc-dirty"}

After df18cd2 was introduced, the output became:

2026/01/06 23:34:20 maxprocs: Updating GOMAXPROCS=1: using minimum allowed GOMAXPROCS
GOMAXPROCS: 1
NumCPU: 32
{"level":"info","ts":1767742460.8121657,"msg":"version: v25.10.1, commit: a36470a50-dirty"}

And with the changes introduced in this PR (using the functionality from the Go standard library), the output is:

GOMAXPROCS: 2
NumCPU: 32
{"level":"info","ts":1767742594.565255,"msg":"version: v25.10.1, commit: 1bd23fe2e-dirty"}

This appears to be the expected behavior according to https://pkg.go.dev/runtime#hdr-Implementation_details-GOMAXPROCS.
