feat(transformer_plugins): support import.meta injection in inject_global_variables

[Copilot]

• Understand the repository structure and inject functionality
• Locate relevant code in inject_global_variables.rs
• Verify existing tests pass
• Add test case for import.meta and import.meta.foo injection
• Extend InjectImport to support import.meta as a special case
• Update dot define replacement logic to handle MetaProperty expressions
• Run tests and verify the fix works correctly
• Ensure all existing tests still pass
• Add comprehensive tests for nested properties and combined cases
• Merge main branch and resolve conflicts

@copilot rebase the PR and resolve the conflict

Rebase completed. The branch has been rebased onto the latest main and conflicts with the new escaping tests have been resolved. All tests pass (23 inject_global_variables tests including 4 new import.meta tests).

However, I cannot force-push the rebased branch as Git authentication is not available in this environment. The rebase is complete locally at commit 2ca7bb7, and the branch needs to be manually force-pushed to update the PR.

• Extended replace_dot_defines method in inject_global_variables.rs to handle Expression::MetaProperty nodes
• Added logic in replace_global_defines.rs to properly match import.meta when checking dot defines
