When using helpers like `random` as subexpressions with the `set` helper
(e.g., `{{set "x" (random (array "a" "b"))}}`), the value was being stored
as a Handlebars SafeString object instead of a plain string, causing
`[object Object]` output and broken conditionals.
The set helper now converts objects with toString() to strings before storing.
Also updates gameshow example to use this pattern for silent random selection,
and adds a test for the subexpression scenario.

… length) Implements feature request from issue #166. These helpers allow managing arrays stored in attributes - useful for tracking items, available options, or game state like rounds that shouldn't repeat. - append: Add element(s) to end of array - prepend: Add element(s) to start of array - pop: Remove and return first element - remove: Remove first matching value - contains: Check if array contains value - length: Get number of elements Also refactored set helper to use shared unwrapValue function, and updated the gameshow example to use these helpers for non-repeating rounds.

When Handlebars template compilation or execution fails, errors are now displayed on screen in a styled error box with monospace font, instead of silently failing with no output. Errors are also logged to the console. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Rename "listVar" to "attribute" to match other helpers, add note explaining the parameter is an attribute name (string), not the array. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
