small polish tasks for release 0.6 on julia1.12 with paper

[Krastanov]

• [x] GraphsMatching does not work on 1.12 due to LEMONGraphs due to cxxwrap recompilation
• [x] remove Prajit's zalm
• [ ] move Gabe's zalm states to separate packages and make sure they are included in the docs
• [ ] the state explorer example should have more states, including both Prajit's and Gabe's zalm state
• [ ] in the state explorer see that the Fidelity does not depend on some of the parameters and just stays at 1 -- check with Gabe whether that makes sense
• [ ] pretty tables in docs do not work well
• [ ] move docs to subfolder instead of a subdomain
• [ ] rename Prajit's zalm source
• [ ] sprinkle references to both published papers throughout the docs
• [ ] use [source] in the docs and examples Project.toml files
• [ ] use [source] for the newly moved Prajit/Gabe extensions
• [ ] simplify the states_rest_server following the TODO in its README
• [ ] finish firstgenrepeater_v2 -- currently it has some unfinished purifier, no readme, no online demo, and a mix of files that create videos as examples and files that run bonito webapps
• [ ] rename firstgenrepeater_v2 to something that makes it more important sounding (because it is one of the few examples of the most modern APIs)
• [ ] a better readme for the examples folder
• [ ] better landing page for areweentangled yet
• [ ] a non-docs front page for the project with multidocs for the other projects
• [ ] the filters like EntanglerProt.chooseA are implemented as Vector->Vector instead of as a boolean predicate, making them non-orthogonal to other features like margin/hardmargin/randomize
