chore(ci): migrate actions to Node.js 24 and upgrade codecov to v5

[diego64]

Summary

• Add FORCE_JAVASCRIPT_ACTIONS_TO_NODE24: true at the workflow level in ci.yml, commitlint.yml, and codeql.yml
• Upgrade codecov/codecov-action from v4 → v5

Root Cause

GitHub Actions currently runs JavaScript actions on Node.js 20 by default. GitHub will force all runners to Node.js 24 starting June 16, 2026 and will remove Node.js 20 on September 16, 2026. The following actions were flagged:

Action	Affected workflows
actions/checkout@v4	ci, commitlint, codeql
actions/setup-node@v4	ci, commitlint
pnpm/action-setup@v4	ci, commitlint
codecov/codecov-action@v4	ci (cobertura job)

Changes

FORCE_JAVASCRIPT_ACTIONS_TO_NODE24: true

Set at the top-level env: block in all three workflow files. This is the opt-in mechanism recommended by GitHub to immediately switch JavaScript action runtimes to Node.js 24, ahead of the forced migration deadline.

codecov/codecov-action@v5

v5 is a major release with native Node.js 24 support. Updated in the cobertura job of ci.yml. No configuration changes required — the files and fail_ci_if_error inputs remain identical between v4 and v5.
