PR #18: License

Summary

Adds Apache 2.0 licensing to the project with automated enforcement tooling and CI updates.

Changes

1. License File & Copyright Headers

• Added standard Apache 2.0 LICENSE file at repo root.
• Prepended Copyright 2026 thumbrise Apache 2.0 header to all .go and .js source files (9 files).

2. License Enforcement Tooling (license-eye)

• Added github.com/apache/skywalking-eyes as a Go tool dependency (go.mod).
• New .licenserc.yaml configures license-eye to:
  • Check Apache 2.0 headers on **/*.go, **/*.js, **/*.ts, **/*.sh.
  • Ignore generated/config files (*.yaml, *.md, go.mod, go.sum, etc.).
  • Scan dependency licenses against go.mod.
• New license task in Taskfile.yaml runs license-eye header fix for local auto-fixing.

3. CI Restructuring (.github/workflows/ci.yml)

• Lint job: Replaced golangci/golangci-lint-action@v9 with manual golangci-lint install + task lint.
  • task lint now runs both golangci-lint and license-eye (dependency check + header check).
  • Note: Lost only-new-issues: true behavior — all existing lint issues will now be reported.
• Both jobs: Replaced unofficial rnorton5432/setup-task@v1 with official go-task/setup-task@v1.

4. Minor Test Refactor (signal/trace/composite_sampler_test.go)

• Simplified a negated compound condition using De Morgan's law:
  • Before: !(Drop < RecordOnly && RecordOnly < RecordAndSample)
  • After: Drop >= RecordOnly || RecordOnly >= RecordAndSample
