fix(angular): ensure table options updates are not missed during first mount window

[riccardoperra]

This pull request addresses a key issue in the @tanstack/angular-table package where options updates could be missed during the initial mount of a table. The changes ensure that option updates are reliably captured from the very first render, and also refactor the lazy initialization logic to provide more robust state tracking and improved test coverage.

Core improvements to options reactivity and initialization:

• The injectTable function now uses a computed signal for options and ensures updates are not missed during the initial mount, fixing a bug where the first update could be dropped. This involves tracking previous options and applying updates only when they change.
• The lazyInit utility is refactored to return an object with value, rawValue, and initialized properties, allowing for more precise control and introspection of the lazy initialization state. [1] [2] [3]

Testing and reliability improvements:

• Additional and updated tests ensure that options updates are not dropped before the effect first runs, and that the new lazy initialization logic behaves correctly and is testable. [1] [2] [3] [4] [5]
• Minor test and type fixes, such as correcting feature spreading and updating test assertions to match the new initialization API.

Documentation:

• A changeset is added to document the patch release and the fix for missed options updates on first mount.
