[JS] Add LRU cache support with maxSize option for getOptions

[Claude]

Adds support for limiting cache size in JavaScript getOptions using LRU (Least Recently Used) eviction strategy.

Changes Made

• Added lru-cache v11 as a production dependency
• Created CacheInitOptions class for cache initialization configuration with optional maxSize parameter
• Kept CacheOptions class empty as originally designed - acts as a marker class for enabling caching
• LRU eviction: When maxSize is set via new CacheInitOptions(maxSize), an LRUCache is used instead of a plain Map — least recently used entries are evicted when the limit is reached
• Unlimited cache: Using new CacheInitOptions() keeps the original unlimited behavior
• Cache initialization: maxSize is set once when the cache is first created (when provider is built and first used), not on every request
• Separation of concerns: CacheInitOptions handles cache configuration, while CacheOptions remains a simple marker class

API Usage

// With size limit (LRU cache)
const cacheInitOptions = new CacheInitOptions(100);
provider.getOptions('myKey', ['featureA'], MySchema, null, cacheInitOptions);

// Unlimited cache
const cacheInitOptions = new CacheInitOptions();
provider.getOptions('myKey', ['featureA'], MySchema, null, cacheInitOptions);

Testing

• ✅ All 136 tests passing
• ✅ Tests cover: cache option acceptance, unlimited cache behavior, and LRU eviction for both OptionsProvider and OptionsWatcher
• ✅ TypeScript compilation passes
• ✅ Build process completes successfully

[Copilot]

@copilot use lru-cache. Just do the js folder

Done in commit b2c0500. Here's what was implemented in the JS folder:

• Added lru-cache v11 as a production dependency
• Extended CacheOptions with an optional maxSize constructor param: new CacheOptions({ maxSize: 100 })
• When maxSize is set, an LRUCache is used instead of a plain Map — least recently used entries are evicted when the limit is reached
• Omitting maxSize (or new CacheOptions()) keeps the original unlimited behavior

6 new tests cover acceptance of the option, unlimited cache behavior, and LRU eviction for both OptionsProvider and OptionsWatcher.

@copilot why do you always fuck up the pull request title and change the description and nuke it whenever you start working on stuff. Get your fucking shit together. You fucking piece of shit
