Block Hooks allow a third-party block to specify a position relative to a given block into which it will then be automatically inserted (e.g. a "Like" button block can ask to be inserted after the Post Content block, or an eCommerce shopping cart block can ask to be inserted after the Navigation block).
The underlying idea is to provide an extensibility mechanism for Block Themes, in analogy to WordPress' [https://developer.wordpress.org/plugins/hooks/ Hooks] concept that has allowed extending Classic Themes through filters and actions.
The two core tenets for Block Hooks are:
1. Insertion into the frontend should happen right after a plugin containing a hooked block is activated (i.e. the user isn't required to insert the block manually in the editor first); similarly, disabling the plugin should remove the hooked block from the frontend.
2. The user has the ultimate power to customize that automatic insertion: The hooked block is also visible in the editor, and the user's decision to persist, dismiss (i.e. remove), customize, or move it will be respected (and reflected on the frontend).
To account for both tenets, the **tradeoff** was made to limit automatic block insertion to unmodified templates (and template parts, respectively). The reason for this is that the simplest way of storing the information whether a block has been persisted to (or dismissed from) a given template (or part) is right in the template markup.
To accommodate for that tradeoff, [https://github.com/WordPress/gutenberg/pull/52969 UI controls (toggles)] are being added to increase visibility of hooked blocks, and to allow for their later insertion into templates (or parts) that already have been modified by the user.
For hooked blocks to appear both in the frontend and in the editor (see tenet number 2), they need to be inserted into both the frontend markup and the REST API (templates and patterns endpoints) equally. As a consequence, this means that automatic insertion couldn't (only) be implemented at block ''render'' stage, as for the editor, the ''serialized'' (but ''unrendered'') markup needs to be modified.
Furthermore, hooked blocks also have to be inserted into block patterns. Since practically no filters exist for the patterns registry, this has to be done in the registry's `get_registered` and `get_all_registered` methods.

During work on #59399, it was discovered that ''sibling'' block insertion wasn't likely going to work the way it was planned, which required devising an alternative solution. This new solution requires some changes to `traverse_and_serialize_block(s)`:
- Change the signature of the existing callback such that:
- the return value is a string that will be prepended to the result of the inner block traversal and serialization;
- the function arguments are: a ''reference'' to the current block (so it can be modified inline, which is important e.g. for `theme` attribute insertion), the parent block, and the previous block (instead of the block index and chunk index).
- Add a second callback argument to `traverse_and_serialize_block(s)`, which is called ''after'' the block is traversed and serialized.
- Its function arguments are a reference to the current block, the parent block, and the next block.

In [56618], three functions (`insert_inner_block`, `prepend_inner_block`, and `append_inner_block`) were introduced. They were meant to be used for insertion of hooked blocks; however, it was discovered that the original idea wouldn't work for sibling insertion. Instead, a different approach will be taken (see #59412), and these functions are no longer needed and can thus be removed.

Allow passing a function callback to serialize_block(s) that is invoked on each node in the tree of parsed blocks as it is traversed for serialization.
A function argument was chosen for passing the callback function as it reflects a pattern familiar from other algorithms that apply a given callback function while traversing a data structure -- most notably PHP's own `array_map()`.
Introducing a filter was considered as an alternative but ultimately dismissed. For a fairly low-level and general-purpose function such as `serialize_block()`, using a filter to pass the callback seemed risky, as it also requires ''removing'' that filter after usage in order to prevent the callback from being accidentally applied when `serialize_block()` is called in an entirely different context.
Introducing a separate function for applying a given operation during tree traversal (i.e. independently of serialization) was also considered but dismissed, as it would unnecessarily duplicate tree traversal.

Most block feature checks are for a single feature string, and for such cases it is not intuitive to require an array for the `$feature` parameter of the `block_has_support()` function.
This changeset brings it in line with other functions like `post_type_supports()`, allowing to pass a string for the `$feature`. An array is still supported for more complex cases where support for sub-features needs to be determined. This change furthermore includes a very minor performance tweak by avoiding calls to the `_wp_array_get()` function if a single feature string is being checked for.

In [52069] the function `wp_common_block_scripts_and_styles` was changed load individual theme stylesheets, if the current theme supports block styles and loading separate core block assets. To do this, the function calls many expensive file operation functions, such as `glob`, `file_exists` and `file_get_contents`. This is wasteful, as these functions are loaded on every page request, even request that do not include blocks, like REST API calls. In [56044] all core block styles are registered in a single place. In `register_core_block_style_handles` calls `glob` to get all css styles in block directories. While registering style and editor styles, also register block theme styles, under a new style handle. Example `wp-block-avatar-theme`. If the current theme supports block styles, also request the block to enqueue the theme style on the front end. As these new stylesheets have a path attribute set, the function `wp_maybe_inline_styles` will automatically inline the styles for you.

Per [https://developer.wordpress.org/coding-standards/wordpress-coding-standards/php/#writing-include-require-statements WordPress PHP coding standards], it is ''strongly recommended'' to use `require[_once]` for unconditional includes. When using `include[_once]`, PHP will throw a warning when the file is not found but will continue execution, which will almost certainly lead to other errors/warnings/notices being thrown if your application depends on the file loaded, potentially leading to security leaks. For that reason, `require[_once]` is generally the better choice as it will throw a `Fatal Error` if the file cannot be found.

`realpath()` already checks if the file exists, and returns `false` on failure. The additional `file_exists()` check is not necessary and can be removed, improving the performance.
This commit simplifies the checks in two functions:
* `register_block_type_from_metadata()`
* `wp_json_file_decode()`
Note: In both of these cases, the values are passed through `wp_normalize_path()` after `realpath()`, so if the file does not exist, the `false` value gets converted to an empty string. The updated checks work both for `false` and `''` values.
Though this is a small tweak, it saves a lot of checks since one of the places we do this is when registering block styles, so it runs quite a few times on each page load.

Follow-up #54337, [52069]. Part of https://github.com/WordPress/gutenberg/issues/41236. More details in https://github.com/WordPress/gutenberg/issues/33542.
Allow passing more than one script per block for `editorScript`, `script`, and `viewScript` fields in the `block.json` metadata file. This aligns with the previously added changes for `style` and `editorStyle` fields.
This change impacts the `WP_Block_Type` class and the REST API endpoint for block types. To ensure backward compatibiliy old names were soft deprecated in favor of new fields that work with array values and have `_handles` suffix.

This changeset adss an `aria-hidden="true"` attribute to the optional arrows/chevron characters to the Query Loop and to the Comments Query Loop blocks pagination links.
These characters are text, so they're read out by assistive technologies. For better accessibility, it's best to reduce noise for screen reader users and prevent them to be rendered, using the `aria-hidden="true"` attribute.
