chore: bump Go to 1.26.0

[peteski22]

Summary

• Update Go version from 1.25.6 to 1.26.0 in go.mod, README.md, and docs/requirements.md
• Bump golangci-lint-action from v8.0.0 to v9.2.0 and golangci-lint from v2.4.0 to v2.10.1 for Go 1.26.0 compatibility

CI workflows already use go-version-file: go.mod so they pick up the Go version automatically.

Closes #248

Test plan

• go test ./... passes
• golangci-lint run passes with v2.10.1
• GitHub Actions workflow verified locally via nektos/act

Summary by CodeRabbit
