perfscan as a golangci-lint plugin

This package exposes perfscan's checks as a golangci-lint module plugin, so you can run them inside your existing golangci-lint pipeline (one binary, unified output).

Build a custom golangci-lint with perfscan

Create .custom-gcl.yml:

version: v2.12.2                                   # your golangci-lint version
name: perfscan-gcl
destination: .
plugins:
  - module: github.com/jxsl13/perfscan/plugin
    version: latest                                # or a plain vX.Y.Z root release

Then golangci-lint custom builds ./perfscan-gcl.

Enable it

In .golangci.yml:

version: "2"
linters:
  enable:
    - perfscan
  settings:
    custom:
      perfscan:
        type: module
        description: "Go performance linter"
        settings:
          maxLevel: 3          # 1=idiomatic, 2=structured, 3=aggressive
          # vocabulary: {...}  # optional; same shape as perfscan.yaml for domain checks

./perfscan-gcl run ./... then reports perfscan findings, e.g.:

a.go:5:20: PS3104: sort.Ints is the legacy spelling of slices.Sort … (perfscan)

The plugin registers every check from perfscan's registry (via checks.All()), so it always exposes the full catalog of the selected root release.
