* move taskchampion-lib to src/tc/lib, remove the rest
* update references to taskchampion
* Use a top-level Cargo.toml so everything is consistent
* apply comments from ryneeverett
* Recommend LSP's in development docs
Per conversation in #3338.
There are already a lot of documented compile options so I think we're
better off suggesting that everybody create a compile_commands.json
whether or not they're using an LSP because it doesn't cost much.
While I was at it it seemed reasonable to mention rust LSP too. Now that
rls is deprecated I'm not sure there is any competitor to rust-analyzer
worth mentioning.
* Export compile commands by default.
Thanks to @felixschurk for the idea and telling me how to do it.
It took me a minute to figure out that this places the
compile_commands.json in the build directory rather than the root of the
project. But clangd still finds it there and that's a better place for
it anyway.
* update build instructions
Usage of "modern" CMake syntax and using specific out of source build.
Further add example on how to build in parallel, build a specific target
and how to change the compiler.
This closes#3236.
* move doc/misc to top level, add READMEs
* Move docs -> doc/devel
This also consolidates the _three_ documents describing (differently)
how to build Taskwarrior into a signle document.
