⚡ [perf] Improves module loading and execution speed

Improves the module's performance by optimizing configuration handling, script inventory, and metadata loading, and introduces a performance playbook.

- ⚡ [perf] Implements lazy loading for cache and configuration:
 -  -  Initializes the cache directory and loads configuration only when needed, avoiding unnecessary overhead during module import.
- ⚡ [perf] Optimizes configuration saving:
 -  -  Adds a check to prevent writing configuration if the content hasn't changed, reducing disk I/O.
- ⚡ [perf] Enhances script inventory management:
 -  -  Caches script inventory and reuses record objects to avoid rescanning the scripts directory on warm calls.
 -  -  Adds function to reset the script inventory cache.
- ⚡ [perf] Improves metadata loading and caching:
 -  -  Adds support for JSON-based metadata cache file for faster subsequent loads.
 -  -  Uses .NET file methods for faster file existence checks and modification time retrieval.
- ⚡ [perf] Optimizes script execution and output handling:
 -  -  Introduces `Test-ColorScriptTextEmission` to determine when to emit text, reducing overhead when output is redirected or not needed.
- 🛠️ [fix] Fixes a regex in `Show-ColorScriptHelp` to correctly match parameter metadata lines.
- 🛠️ [fix] Corrects an issue where the configuration root path could be improperly determined if XDG_CONFIG_HOME was empty.
- 🚜 [refactor] Refactors `Copy-ColorScriptHashtable` and `Merge-ColorScriptConfiguration` to use `System.Collections.IDictionary` instead of `hashtable` for broader compatibility and adds cloning for arrays and ICloneable objects.
- 📝 [docs] Adds a `PERFORMANCE_IMPROVEMENTS.md` file, detailing performance objectives, optimizations, startup timeline, measurement playbook, usage recommendations, maintenance checklist, and future opportunities.
- 🧹 [chore] Updates the linting script to resolve paths and handle potential `NullReferenceException` during analysis.
- 🧹 [chore] Renames an ANSI file to correct character encoding.
