fix(linter/vitest): Optimize hoisted_apis_on_top rule to only check first member

[sidharthv96]

Fixes the vitest/hoisted_apis_on_top to check only if the first member is a hoisted api.
This removes false positives like vi.mocked(something).mock... being flagged as hoisted.

Rule introduced in #17658

[Copilot]

Pull request overview

Updates the vitest/hoisted_apis_on_top linter rule to avoid false positives by only treating a call as “hoisted” when the first member in the vi.* chain is a hoisted API (e.g., mock, hoisted, unmock), matching Vitest’s intended behavior.

Changes:

• Change hoisted-API detection from “any member in the chain” to “only the first member”.
• Add regression tests ensuring vi.mocked(...).mock.calls... chains are not flagged.
