fix(test): point USERPROFILE at the temp home on Windows

[anhtahaylove]

Two tests in test/slots-flag-gate.test.ts fail on Windows for anyone whose own ~/.agentmemory/.env sets AGENTMEMORY_SLOTS or AGENTMEMORY_REFLECT to false.

Cause

beforeEach creates a temp home and points HOME at it, but src/functions/slots.js resolves the config path through os.homedir() — and on Windows that reads USERPROFILE, ignoring HOME entirely:

> process.env.HOME = 'C:/tmp/fake-home'
> os.homedir()
'C:\Users\Administrator'

So the flag is read from the developer's real .env rather than the temp file the test just wrote. CI is green because HOME and USERPROFILE agree on Linux.

Fix

Set USERPROFILE alongside HOME in both describe blocks and restore it in afterEach.

Verification

On a clean checkout of main, Windows:

before: Tests  2 failed | 2 passed (4)
after:  Tests  4 passed (4)

slots-flag-gate is the only test file that overrides HOME without USERPROFILE — the other nine already set both, so this brings it in line with them.

Summary by CodeRabbit

• Tests
  • Improved cross-platform test reliability by ensuring temporary home-directory settings work correctly on Windows.
  • Added cleanup to restore the original environment after each test.

📝 Walkthrough

Walkthrough

The test setup now controls both HOME and USERPROFILE. This ensures os.homedir() uses the temporary directory on Windows. Each test restores the original environment values.
