test: add property tests for async utilities (Phase 4)

[BYK]

Summary

Phase 4 of our model-based/property-based testing initiative. Adds property tests for async utilities that handle polling and concurrent operations.

Changes

New Files

• test/lib/polling.property.test.ts - 8 property tests for poll() function
• test/lib/promises.property.test.ts - 8 property tests for anyTrue() function

Test Coverage

poll() properties:

Property	Description
Immediate return	Returns immediately when shouldStop is true on first fetch
Stop predicate	Returns state that satisfies shouldStop predicate
Timeout behavior	Throws timeout error when shouldStop never returns true
Bounded fetch count	Number of fetchState calls ≤ timeout/interval + tolerance
Null handling	Null fetchState results are skipped until valid state
Progress updates	Progress message is updated from state
Immediate timeout	Handles timeoutMs = 0 edge case
Error propagation	fetchState errors propagate correctly

anyTrue() properties:

Property	Description
Correctness	Returns true iff any predicate returns true
Empty array	Empty array always returns false
Single element	Single-element result equals predicate result
Error handling	Errors in predicates are treated as false
All errors	All predicates throwing returns false
Order independence	Result doesn't depend on predicate completion order
All false	All false predicates return false regardless of timing
Completeness	Predicate called for each item when no early true
