Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Re-targeting (Lisp) compilers
Clasp notably uses Cleavir which is “an implementation-independent framework for creating Common Lisp compilers”.

Flexible intrinsics for my minimal code generator
I think something similar has come up with the Cleavir framework; there are currently separate instruction types for arithmetic operations, but it has been proposed to replace them with fewer types, because there is little use in specific types. Register allocation is specified the hard way currently, while as you say, the complexity even for x86-64's multiplication and division instructions is just in forcing use of the right input and output registers.

Clasp reaches 1.0 (Common Lisp with C++ Interop)
This is a project that has been in development for years now and also makes use of the Cleavir compiler framework (https://github.com/s-expressionists/Cleavir), which is being developed as part of another new Common Lisp implementation called SICL (https://github.com/robert-strandh/SICL).
Congrats to the CLASP devs, this is a huge accomplishment and it's really exciting to see a new CL implementation get a 1.0 release.

Csexp: S-Expressions over the Network
I think this should be safe: https://github.com/phoe/safe-read
This doesn’t provide such functionality out of the box, but it makes it pretty trivial to produce a custom READ that only has the features you want: https://github.com/s-expressionists/Eclector

Re-targeting (Lisp) compilers
There is significant overlap with SICL and its associated pieces which supply many of the other parts needed to make a Common Lisp. Some of these are Cluster which provides a portable and extensible assembler, Eclector which supplies a portable and extensible reader, Concrete-Syntax-Tree that supports source code tracking during compilation, ctype that implements the Common Lisp type system, and Clostrum that provides first-class environments for e.g. run-time, evaluation, and compilation. The SICL project has as one of its goals the creation of portable infrastructure for implementing Common Lisp, and these pieces are novel building blocks that were created as part of the project.

Are there public experiments with parallel and concurrent lisp 'engines'?
You mean the parts of the reader that is capable of reading from a stream object and returns strings, booleans, numbers? These are just functions that accept a stream and they return Lisp objects. See e.g. Eclector for an implementation of a Lisp reader as an external library.

Lowercased version of Common Lisp with case preserving readtable (:PRESERVE)
I'm aware of eclector; hoping to take a look some day.
What are some alternatives?
SICL - A fresh implementation of Common Lisp
ctype - CL type system implementation
lparallel - Parallelism for Common Lisp
Clostrum - First Class Global Environments
nyxt - Nyxt - the hacker's browser.
luckless - Lockless data structures for Common Lisp
wat-js - Concurrency and Metaprogramming for JS
cl-secure-read - Securing a reader in spirit of Let Over Lambda
Cluster - Assembler with input in the form of standard instances
