In kate there seems to be "dynamic" and "static" word wrap options in view -> word wrap and settings -> configure kate -> editing -> general respectively.
"Static" is off by default while "dynamic" is on. Turning off "dynamic" gives the behaviour I want (i.e. no word wrap… of any kind). However, this option seems to be per file.
How can I disable word wrap in the kate text editor for all files and have that option persist?
Once you have CTags installed
sudo apt-get install exuberant-ctags
Activate the plugin by going to Settings -> Configure Kate...
Then when the window pops up, click Application -> Plugins and check "CTags"
Next in Kate's Index Targets tab pane, click Add and enter the /path/to/project/root, then click Update Index
Now you will be able to use the CTags.
Notice the Database tab pane is where you can set the CTags command. See the man pages for options. Generally, I like to exclude my dependency package folders by adding:
--exclude=vendor --exclude=node_modules
No need to put anything in the "CTags Database File" field because Kate will automatically generate this file when you click Update Index
Note that you can, but do not need to create a .kateproject file to use the CTags.

There is another setting you need to turn off.
Uncheck the checkbox in
settings -> configure kate -> Editor Component -> Appearance -> Dynamic Word Wrapand it should now work the way you want.
