Adding manual tests list

[navya9singh]

After tests are generated with npm run convertfourslash, if we need to edit them manually, then this script can be run by
npm run manualtest testname. This creates a manual folder under fourslash/tests/ and adds the name of the test to manualTests.txt.

• All tests in manualTests.txt will ne skipped and not regenerated when convertfourslash is run again.
• Once a manual folder is created, testOutput = cp.execFileSync(go, ["test", "./internal/fourslash/tests/gen"], ["test", "./internal/fourslash/tests/manual"], { encoding: "utf-8" }) can be added to updateFailing.mts to run all the tests under ./manual and update failingtests.txt accordingly.

Pull Request Overview

This PR adds functionality to manually manage fourslash tests by creating a script that moves generated tests to a separate manual directory and tracks them to prevent regeneration. The purpose is to allow developers to edit auto-generated tests without losing changes when the conversion script runs again.

Key changes:

• Adds a new npm script makemanual that moves tests from generated to manual directory
• Implements tracking of manual tests to skip them during regeneration
• Updates the conversion script to respect manual test exclusions

The script exits with code 1 when no arguments are provided, but doesn't provide any error message to explain what went wrong or how to use the script correctly.
