Three problems with the previous server-side approach:
1. wildcard_choices() called get_wildcard_manager() (full disk scan) on
every INPUT_TYPES call, causing massive slowdown with large datasets.
2. Node execution went from ~0.2s to ~4.33s for the same reason.
3. Appending to the template server-side is wrong — selection should
insert __name__ into the template textbox widget in the browser.
Fix:
- Remove wildcard_append from all Python nodes and wildcard_choices()
from wildcards.py, restoring original execution performance.
- Add GET /dynamic_prompts/wildcards API route returning list_names()
as JSON (loaded once per session, not per execution).
- Add web/wildcards.js extension that fetches the wildcard list once,
injects a serialize:false COMBO widget into each node, and on
selection appends __name__ to the template widget then resets.
- Register WEB_DIRECTORY = "web" in __init__.py.
