Pull request overview

This PR updates the project’s test runner setup to support Mocha 12 and modernizes related runtime/test harness behavior, including Node.js version gating and more deterministic test isolation.

Changes:

• Switch Mocha execution to a repo-level config (test/mocha/unit.cjs) with shared bootstrap + root hooks (Chai plugins, env defaults, sandboxed cwd/env, sinon restore).
• Refactor Node logging initialization to be an explicit function (improves testability) and adjust tests accordingly.
• Tighten Node.js support checks to a semver range and update CLI messaging, docs, and CI workflows to match.

test/unit/src/cli/is-supported-node-version.test.js	Updates unit tests for new semver-based Node support range behavior.
test/unit/src/Context.test.js	Small test refactor to create fresh Context instances per test.
test/unit/components/framework/index.test.js	Removes redundant Chai plugin wiring and uses chai.expect.
test/unit/bin/serverless-compose.test.js	Aligns expectations with new Node support messaging and runComponents(argv) signature.
test/mocha/unit.cjs	Adds Mocha config file (spec, requires, timeout, node options).
test/mocha/runtime-sandbox.cjs	Adds suite-wide sandbox for cwd/env/argv/EvalError state and cleanup.
test/mocha/root-hooks.cjs	Adds Mocha root hooks to restore sandbox state and run sinon.restore().
test/mocha/bootstrap.cjs	Centralizes chai-as-promised/sinon-chai registration and sets env defaults used by tests.
test/lib/setup/restore-env.js	Removed (replaced by Mocha root hooks + runtime sandbox).
test/lib/setup/patch.js	Removed (replaced by Mocha config/node options and root hooks approach).

src/utils/serverless-utils/log-reporters/node.js	Refactors log initialization into an injectable function and returns derived state.
src/state/LocalStateStorage.js	Stops using process.cwd() internally; now uses provided root for state dir.
src/index.js	Moves logging setup into runComponents(argv) and passes cwd explicitly to config resolver.
src/configuration/resolve-path.js	Accepts an explicit cwd parameter for better testability/control.
src/cli/is-supported-node-version.js	Uses semver + exported supported range to validate Node versions.
src/Context.js	Ensures root resolution handles missing root more directly; passes root into LocalStateStorage.
src/ComponentsService.js	Makes local component path resolution depend on context root instead of process.cwd().
package.json	Switches test command to Mocha config; bumps Mocha to a v12 beta; updates Node engine range; removes inline Mocha config block.
bin/serverless-compose	Updates unsupported Node messaging and passes argv explicitly into runComponents.
README.md	Updates documented Node.js requirement to the new supported range.
.gitignore	Limits lockfile ignores to repo root (/package-lock.json, /yarn.lock).
.github/workflows/tests.yml	Updates actions versions, cache strategy, and install command to align with no-lock installs and new Node targets.
.github/workflows/publish.yml	Updates actions versions, cache strategy, and install command similarly for publishing pipeline.
