+<#
+.SYNOPSIS
+    Sets ModuleVersion in IdLE module manifests under ./src to a target version.
+
+.DESCRIPTION
+    This script searches for PowerShell module manifest files (*.psd1) under the repository's "src" folder
+    and updates the "ModuleVersion" field to the provided target version.
+
+    The script is intended for release preparation (e.g., bumping all shipped modules to v0.2.0).
+    It is designed to be deterministic, safe to run multiple times (idempotent), and to support -WhatIf/-Confirm.
+
+.PARAMETER TargetVersion
+    The version string to set as ModuleVersion (e.g., 0.2.0 or 0.2.0.0).
+
+.PARAMETER RepoRootPath
+    The repository root path. Defaults to the parent directory of the script folder (../).
+
+.PARAMETER IncludeAllPsd1
+    If set, searches all *.psd1 under ./src recursively.
+    If not set (default), the script only updates manifests that match the pattern ./src/<ModuleName>/<ModuleName>.psd1.
+
+.PARAMETER CreateBackup
+    If set, creates a .bak copy next to each modified manifest before changing it.
+
+.EXAMPLE
+    PS> pwsh -NoProfile -File ./tools/Set-IdleModuleVersion.ps1 -TargetVersion 0.2.0 -WhatIf
+
+.EXAMPLE
+    PS> pwsh -NoProfile -File ./tools/Set-IdleModuleVersion.ps1 -TargetVersion 0.2.0 -CreateBackup
+
+.NOTES
+    - The script uses a conservative regex replace for the ModuleVersion line.
+    - It does not attempt to parse PSD1 into a hashtable, to avoid formatting churn.
