test: give each terminal taxonomy case its own timeout budget

[aviggiano]

The package validation job on main failed because one terminal-taxonomy test performed six sequential durable writes under a single five-second Vitest timeout. It exceeded that budget on the CI runner while the other 654 Modal tests passed.

Parameterize the six categories so each has its own fixture and normal timeout. Retain every category assertion and additionally compare both persisted terminal files with the returned contract. Production behavior and timeout settings are unchanged.

Validation: the focused worker-result tests and the complete Modal suite pass on Node.js 24.20.0, matching CI. Prettier, ESLint, and git diff --check pass.

Greptile Summary

This PR parameterizes the terminal-taxonomy test so each durable-write category receives an independent timeout budget.

• Retains coverage for all six terminal categories.
• Gives each case an isolated temporary root and writer.
• Verifies both persisted terminal files equal the returned contract.

Confidence Score: 5/5

The PR appears safe to merge because the parameterization is valid and preserves the relevant terminal persistence and generation coverage.

Each terminal category now receives a separate test timeout and fixture, while synchronous contract reads occur only after both durable writes complete; no actionable regression was identified.
