[WRONG BRANCH] test(cli): make logout non-mutation sentinel adversarial

[luvs01]

Motivation

• Fix a vacuous non-mutation assertion in the logout regression test where seeding only claude could let a rewrite that removed --json go undetected.

Description

• Change the test seed helper to accept a provider name so the test can seed the exact adversarial token instead of always seeding claude.
• Update the explanatory comment to clarify that the seeded credential must match the provider token that malformed parsing could remove.
• Seed --json in the specific logout test so any erroneous removeCredential("--json") will change the auth file bytes and fail the assertion.

Testing

• Ran the focused test with bun test tests/cli-dispatch.test.ts -t 'a flag is never read as a provider name and leaves the store byte-identical', which passed (1 test, 5 assertions).
• Ran the file-level suite with bun test tests/cli-dispatch.test.ts, which passed (25 tests, 108 assertions).
