Update fork and release instructions in contribution docs

Replaced placeholder GitHub repo references with 'YourUsername/YourRepo' throughout documentation for clarity. Expanded explanations in FORK_SETUP.md and README.md to clarify the difference between development and production script execution, and emphasized the importance of cherry-picking only relevant files for PRs. Updated install script template examples to use the new repo placeholder.

 ### Why Updating Curl Links Matters
 
-When you test scripts locally during development, the `curl` commands in your scripts need to pull from YOUR fork, not the upstream repository:
+Your scripts contain `curl` commands that download dependencies from GitHub (build.func, tools.func, etc.):
 
 ```bash
-# During local testing, after setup-fork.sh runs:
-bash ct/myapp.sh
-# This will curl from: github.com/YOUR_USERNAME/ProxmoxVE/main
-# NOT from: github.com/community-scripts/ProxmoxVE/main
+# First line of ct/myapp.sh
+source <(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/misc/build.func)
+```
 
-# Once merged to upstream and published, users run:
-bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/myapp.sh)"
+**WITHOUT setup-fork.sh:**
+- Script URLs still point to `community-scripts/ProxmoxVE/main`
+- When you test `bash ct/myapp.sh` locally, it downloads from the **upstream** repo, not your changes
+- Your modifications aren't actually being tested! ❌
+
+**AFTER setup-fork.sh:**
+- Script URLs are updated to `YourUsername/ProxmoxVE/main`
+- When you test `bash ct/myapp.sh` locally, it downloads from **your fork**
+- You're actually testing your changes! ✅
+
+```bash
+# Example: What setup-fork.sh changes
+
+# BEFORE (points to upstream):
+source <(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/misc/build.func)
+
+# AFTER (points to your fork):
+source <(curl -fsSL https://raw.githubusercontent.com/john/ProxmoxVE/main/misc/build.func)
