feat: [CI-18487]: Glob pattern support for PLUGIN_STRIP_PREFIX

[DevanshMathur19]

Enhanced PLUGIN_STRIP_PREFIX with Glob-Aware Wildcard Support

This PR enhances the PLUGIN_STRIP_PREFIX functionality by adding wildcard pattern support, allowing dynamic path stripping without relying on shell scripting.

---

Key Features

• Wildcard Patterns: Supports *, **, and ? for flexible path matching

• Backward Compatible: Existing literal path prefixes continue to work as-is

• Robust Validation: Comprehensive checks ensure invalid patterns are rejected gracefully

• Added Unit Tests to test the working for all types of glob paths.

🔧 Wildcard Syntax

Wildcard	Description	Regex Equivalent
*	Matches exactly one path segment	[^/]+
**	Matches zero or more segments	.*
?	Matches exactly one character	[^/]

For the above testing correct directories were created:

[Ompragash]

• add tests for windows/backslash inputs with validation. add a test that mimics
  Exec() validation on windows-style patterns ensuring normalization/anchoring works as intended

• update readme to show wildcard examples and clarify trailing / meaning

• add a log to show what would be stripped in dryrun mode

• also log once when no path matches the strip pattern

This breaks existing use with relative paths like foo/ which fail with strip_prefix must start with '/'.

Thanks, @silverwind, for pointing this out! These changes have been reverted, and they'll be fixed in the next iteration.
