Subject: refactor(devtools): rename dev_tools to .run and replace run-tools
 scripts

Replace the old run-tools.ps1/run-tools.sh scripts with a new
unified run.ps1/run.sh launcher that supports multiple languages
(PowerShell, Rust, Python, Go, C#, Nim, Perl, Ruby, Zig, and
arbitrary binaries) from the `.run/src/bin` directory.

Move all development tools from `dev_tools/` to `.run/`, update
Cargo workspace config and relevant documentation references.
