[Feature] add a SEARCH feature in the workflow

### Is there an existing issue for this?

- [x] I have searched the existing issues and checked the recent builds/commits

### What problem are you experiencing?

Big workflow = lot of nodes => take time to find that tiny value you want to change.

### When does this problem occur?

Whenever I want to change some little values.

### How often do you encounter this problem?

Multiple times per day

### How much does this problem affect your workflow?

Significantly slows down my work

### Current workarounds

My speed would increase if I was able to just ctrl F and change things
For example "where is that CFG value people are changing on this specific workflow and experimenting with"?
Id rather ctrol F and be teleported to different nodes.

No files, tests, or entry points are named. Start by locating the workflow editor's node navigation and existing keyboard-shortcut or search handling, then define how matching values select or reveal nodes. Done should include a specified search interaction that finds the requested workflow value and moves to the relevant node.
