Description: Addresses four correctness issues identified in PR #16 code review: Changes bq-class directive - Changed array detection from expression.includes('[') to /^\s*\[/.test(expression) to distinguish array literals from bracket property access (foo['bar']) once() utility - Set hasRun = true after function execution instead of before, preventing cached failures when fn() throws mount() validation - Added check to reject mounting on elements with bq-for directive, preventing View.el from becoming detached when the directive replaces the element with a placeholder comment Component lifecycle - Added hasMounted flag to gate attributeChangedCallback() renders until after connectedCallback() completes, preventing double renders and bypassed prop validation during element upgrade // Before: this would incorrectly trigger array branch

// After: correctly evaluates as single expression
// Array literals still work
Test Coverage Comprehensive test coverage has been added for all four fixes to prevent regressions: once() utility tests - Verifies that failures are not cached and the function retries on subsequent calls until success bq-class directive tests - Verifies bracket property access like item['className'] is handled correctly and not confused with array literals ['foo', 'bar'] mount() validation tests - Verifies mounting on elements with bq-for throws with clear error message instructing to wrap in container Component hasMounted tests - Verifies no renders occur when attributes are set before connectedCallback, and only one render happens on mount even during element upgrade Total: 12 new test cases added across 3 test files (tests/utils.test.ts, tests/view.test.ts, tests/component.test.ts) 💬 We'd love your input!
