Test Plan

• make unit-test
• make test
• go mod tidy (no go.mod / go.sum changes)
• go run github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.1.6 run --new-from-rev=origin/main

Summary by CodeRabbit

Release Notes

• Chores
  • Added copyright headers and MIT SPDX license identifiers to multiple files across authentication, credential management, keychain integration, virtual file system utilities, and scripting modules to maintain consistent licensing documentation and comprehensive legal compliance standards throughout the codebase. These administrative updates do not affect any runtime functionality, user-facing features, or public API surfaces.

Greptile Summary

This PR adds the standard // Copyright (c) 2026 Lark Technologies Pte. Ltd. / SPDX-License-Identifier: MIT header to 20 files across cmd/auth, extension/credential, internal/credential, internal/keychain, internal/vfs, and scripts/issue-labels that were missing it. The format, copyright year, and placement (including ordering before //go:build constraints in build-tag files) are fully consistent with every other file in the repository.

Confidence Score: 5/5

Safe to merge — purely additive license header changes with no logic modifications.

All 20 files receive the correct, repo-standard MIT header. The copyright year (2026), SPDX identifier, and header placement (including ordering relative to //go:build constraints) are fully consistent with the rest of the codebase. No logic is touched.

No files require special attention.

Vulnerabilities

No security concerns identified. This PR only adds license header comments; no logic, secrets, or data handling is changed.
