This PR inverts the execution model -- from recursively calling nodes to
using a topological sort of the nodes. This change allows for
modification of the node graph during execution. This allows for two
major advantages:
1. The implementation of lazy evaluation in nodes. For example, if a
"Mix Images" node has a mix factor of exactly 0.0, the second image
input doesn't even need to be evaluated (and visa-versa if the mix
factor is 1.0).
2. Dynamic expansion of nodes. This allows for the creation of dynamic
"node groups". Specifically, custom nodes can return subgraphs that
replace the original node in the graph. This is an incredibly
powerful concept. Using this functionality, it was easy to
implement:
a. Components (a.k.a. node groups)
b. Flow control (i.e. while loops) via tail recursion
c. All-in-one nodes that replicate the WebUI functionality
d. and more
All of those were able to be implemented entirely via custom nodes,
so those features are *not* a part of this PR. (There are some
front-end changes that should occur before that functionality is
made widely available, particularly around variant sockets.)
The custom nodes associated with this PR can be found at:

Note that some of them require that variant socket types ("*") be
enabled.
* Fix render on change not respecting auto queue checkbox
Fix issue where autoQueueEnabled checkbox is ignored for changes if autoQueueMode is left on `change`
* Make check more specific
* Add toggle to enable auto queue when graph is changed
* type fix
* better
* better alignment
* Change undoredo to not ignore inputs when autoqueue in change mode
- Implemented a `try-except` block in the `recursive_search` function to handle `FileNotFoundError` gracefully.
- When encountering a file or directory path that cannot be accessed (causing `FileNotFoundError`), the code now logs a warning and skips processing for that specific path instead of crashing the node (CheckpointLoaderSimple was usually the first to break). This allows the rest of the directory traversal to proceed without interruption.
