feat: Many small features and chores

[puma314]

• [docs] update tiny-keccak in docs to not be succinctlabs in patches section
• [docs] add cycle tracker documentation + cycle tracking example
• [docs] in patching, tell people how to know whether patch is being applied by looking at the events
• [cli] in default assets, add [build.rs](http://build.rs) + .vscode/settings.json
  • test new cli/assets
• [runtime]: make sure to buffer stdout and wait for println before flush
  • test
• [runtime]: halt has exit code
  • test

Now during program execution, if there is a panic, then the logger will show this

$ cargo run --release

RISC-V runtime halted during program execution with non-zero exit code 1. This likely means your program panicked during execution.
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I also changed it so that during runtime execution, it directly prints to stderr/stdout instead of logger, but I'm open to changing this back:
