TidalShell support, now tested.(extends #2428)

[cerealdevv]

Summary

This PR adds native version detection and proper process tree handling for TidalShell (https://github.com/c-cluster/TidalShell).
This PR is a repost of the pull #2428
it has now been tested locally on Windows x64

Changes

• terminalshell.c: Added getShellVersionTidalshell helper. It invokes tidalshell -v (introduced in TidalShell 0.2-Nightly), trims trailing spaces, and isolates the numeric version by stripping out build tags (e.g., -Nightly).
• terminalshell_linux.c: Added tidalshell to the known shells ignore array inside getTerminalInfo. This prevents Fastfetch from misidentifying the shell as a terminal emulator on Linux systems.
• terminalshell_windows.c: Added proper case mapping in setShellInfoDetails so the UI cleanly displays TidalShell.

Checklist

• I have tested my changes locally.

Notes for Reviewers

Please review my code. as I stated, I am not primarily a C/C++ developer. I am not as experienced in it.
I do not know if my code is efficient nor if it meets fastfetch quality standards.
