Time-travelling based debugger
Is your feature request related to a problem? Please describe.
I love rr's time-travel-based debugger idea but I like cutter and the rizin/r2 philosophy framework a ton.
Describe the solution you'd like
I'd like a rr-style time-travel debugger, implemented to fit rizin.
rr apparently supports IDEs with it's gdb interface (https://github.com/rr-debugger/rr/wiki/Using-rr-in-an-IDE).
So either it is already possible to use it or it shouldn't be too difficult to add. But I am not familiar with RzDebug.

this requires rzil. this can be easily implemented as rzil events and stored in frames.
I think there is an issue about this somewhere? @notxvilka

Yes:

If we speak about the backward step and recording, Rizin already supports it - see dsb and dts commands. It is experimental and could be better tested and improved.
See the corresponding chapter of the book: https://book.rizin.re/src/debugger/revdebug.html

Yes, backward stepping is present in the debugger for some archos combinations IIRC
The session is maintained through RzDebugSession, but I havent really worked with it till now. For each function (lets stay stepping) we have a different implementation when in a session and different for normal one
Maybe refactor RzDebugSession such that it by default works for normal one, but when a session is started for recording, it initalizes some if its values and then works for backward stepping etc? and add better testing
