Add EnableLLMKit option to InstallMCPServer

[rhennigan]

Summary

Adds an "EnableLLMKit" option to InstallMCPServer, following the existing "EnableMCPApps" pattern: the option sets an LLMKIT_ENABLED environment variable in the MCP config, which is checked at runtime.

Value	Behavior
Automatic (default)	Equivalent to True — no env var injected; LLMKit works as before
True	LLMKit features enabled
False	Injects LLMKIT_ENABLED=false. The context tools (WolframContext, WolframAlphaContext, WolframLanguageContext) then behave as if the user has no LLMKit subscription — unfiltered documentation, no Wolfram|Alpha semantic results — but with no subscription warnings, and the install-time subscription check is skipped

Implementation

• Runtime gate — new llmKitEnabledQ[] (Utilities.wl, declared in CommonSymbols.wl) reads LLMKIT_ENABLED, mirroring mcpAppsEnabledQ. The no-arg llmKitSubscribedQ[] now short-circuits to False when disabled, so it never even makes the cloud lookup and every context tool takes the unsubscribed path.
• Warning suppression — relatedWolframAlphaPrompt[…, False] returns "" when LLMKit is disabled (vs. the subscribe-here message when genuinely unsubscribed), so the combined tool just omits the Wolfram|Alpha section.
• Install-time — $enableLLMKit config var + Block bindings; addEnvironmentVariables injects the env var on False; a guard clause on checkLLMKitRequirements returns None when disabled. Injection is centralized, so all client formats (Codex, Goose, Continue, Augment, generic) get it.

Test plan

All tests pass (100%) across the affected suites (run via the TestReport MCP tool / wolframscript -f Scripts/TestPaclet.wls Tests/<file>.wlt). New tests cover:

• llmKitEnabledQ — env-var truth table (unset → enabled; false/False/FALSE → disabled; other values → enabled).
• llmKitSubscribedQ gating — returns False when disabled and short-circuits before getLLMKitInfo[] (no cloud lookup).
• Install env injection — LLMKIT_ENABLED=false present for EnableLLMKit -> False; absent for default / True / Automatic.
• Requirement-check guard — with EnableLLMKit -> False, checkLLMKitRequirements returns None without consulting llmKitSubscribedQ (a WolframAlpha-required tool installs without a subscription failure).
• Context-tool behavior — disabled ⇒ docs returned, no subscription nag; regression guard: a genuinely unsubscribed user (LLMKit enabled) still gets the warning + buy-now URL.
• environmentBlock test helper — self-test confirms it sets and restores the real process environment.

CodeInspector is clean on all modified source files.

Pull request overview

This PR introduces an "EnableLLMKit" option to InstallMCPServer to control whether LLMKit-backed context-tool behavior is enabled for an installed server by injecting LLMKIT_ENABLED=false into the server environment, mirroring the existing "EnableMCPApps" pattern.

Changes:

• Added runtime gating via llmKitEnabledQ[] and updated llmKitSubscribedQ[] to short-circuit when LLMKit is disabled.
• Updated context-tool behavior to suppress subscription warnings/WA section when disabled.
• Added/updated tests and documentation for the new option and environment variable.
