refact: categorize dev scripts & add zed editor installation

[jeevithakannan2]

Type of Change

• New feature
• Refactoring

Description

• Added zed editor installation script.

Note

Chores:

• The chores are not related to this PR. Instead of creating a separate PR it was done here itself.
• Refactor Developer-tools directory to developer-tools (Kind of annoying for developers to hold shift every time when typing D)
• Refactor file names inside developer-tools from application-setup.sh to application.sh as all the scripts inside the directory is supposed to setup that particular application. No need of mentioning it in the name.
• The chores are of separate commits @ChrisTitusTech If you wish not to do this we can easily revert the commits.

Testing

• Tested on arch linux and debian12 without issues.

This is to make no conflicts with PR #888

[jeevithakannan2]

That suggestion is wrong.

[jeevithakannan2]

You suggestion is interpreted as command_exists foo1 || command_exists foo2

[jeevithakannan2]

This will not check both foo1 and foo2 .It will immediately return 1 if foo1 is not found

[jeevithakannan2]

removing the && would simplify it since && is redundant due to #762 having both && and not having && is the same but, && is redundant due to #762

That's what I have explained above. #762 will work as || not as &&

Rebasing is often preferred, just fyi

Too many merges make git log way to complicated to understand/bisect if needed.
