fix(cli): make tests OS-agnostic by normalizing path separators

[mukund-2114]

Fixes #1280

Summary

On Windows, several CLI tests failed due to backslash vs forward slash path separators in expected vs received values. This PR normalizes path strings in test assertions so comparisons are OS-agnostic.

• Scope: tests-only
• Runtime/API changes: none

Changes

• packages/cli/src/cli/utils/buckets.spec.ts
  • Normalize pathPattern to POSIX-style before equality assertions.
• packages/cli/src/cli/utils/find-locale-paths.spec.ts
  • Normalize arrays of path patterns in the xcode-xcstrings test case.
• .changeset/soft-melons-sin.md
  • Patch bump for lingo.dev with: “fix(cli): normalize path separators in tests for Windows”.

Rationale

Path separators differ across OSes. Normalizing in tests ensures consistent behavior across Windows/macOS/Linux without touching runtime code.

Test Plan

Environment: Windows 11, Node v22.19.0, pnpm 9.12.3

Steps:

1. pnpm install
2. pnpm -C packages/cli test

Results:

• Test Files: 41 passed
• Tests: 554 passed

Optional: See Issue for failure screenshots before this change.

Breaking Changes

None.

Pull Request Overview

This PR fixes test failures on Windows by normalizing path separators in test assertions. The tests were failing because Windows uses backslashes while the expected values used forward slashes. The fix ensures tests pass on all operating systems without modifying runtime code.

Key changes:

• Added helper functions to normalize path separators to POSIX-style (forward slashes) in test assertions
• Applied normalization to test results before comparison in buckets.spec.ts and find-locale-paths.spec.ts
• Added changeset documenting the patch fix
