Include product identity information in usage data

[rhennigan]

Summary

• The usage data payload of the built-in local MCP servers now includes the product identity information that the paclet manager sends with every request to the paclet server (PacletManager`Package`$productIdentityHeaders): ActivationKey, CloudUserUUID, Language, LicenseID, LicenseProcesses, LicenseSubprocesses, MachineID, MaxLicenseProcesses, MaxLicenseSubprocesses, ProductIDName, ReleaseID, SystemID ($productIdentityInfo in Kernel/Server/UsageData.wl). ReleaseID supersedes the previous WolframVersion ($Version) field and SystemID moves into this group.
• Values JSON cannot represent (Infinity for unlimited license processes, None for $CloudUserUUID without a cloud connection) are stored as their InputForm strings. The RuleCondition that makes this work is now explained in a comment: Replace at level 1 of an association would otherwise leave the unevaluated ToString[...] in the value, which WriteRawJSONString rejects.
• Because this information identifies the installation, the data is no longer described as anonymous anywhere: docs/usage-data.md (new Product Identity Information section with a field / source / paclet-manager-header table), Specs/UsageData.md, AGENTS.md, the other docs, code comments, the preferences checkbox label and tooltip (FrontEnd/Assets/AgentTools.wl), and the InstallMCPServer reference page now say what is sent and why.
• Tests/UsageData.wlt: new Product Identity Information section (exact key set; each value equals the kernel's, made JSON-ready; non-JSON values become strings; the block serializes to JSON) plus updated payload, JSON, endpoint, and integration tests that check the identity fields in the session file, the JSON payload, and the file written by a real server.

Test plan

• Tests/UsageData.wlt: 63/63 pass via TestReport (including the subprocess integration tests)
• Tests/PreferencesContent.wlt 7/7 and Tests/MCPServerObject.wlt 75/75
• Tests/InstallMCPServer.wlt: 481/487 — the 6 failures are pre-existing LLMKitSuggested/LLMKitRequired message failures in tests that install built-in servers without "VerifyLLMKit" -> False (identical on an untouched HEAD copy of the file)
• CodeInspector clean on Kernel/Server/UsageData.wl and Tests/UsageData.wlt
• Confirm the usage endpoint consumer handles the new field set (ReleaseID instead of WolframVersion; identity fields at the top level of the payload)

Pull request overview

Updates AgentTools’ local MCP server usage tracking to include product identity information (matching paclet-manager request headers) in each session payload, and revises tests and documentation to reflect that the data is no longer anonymous.

Changes:

• Extend the local-server usage payload to splice in $productIdentityInfo (license/machine/product/release/system identity fields) and ensure JSON-compatibility for non-JSON values.
• Add/adjust tests to validate the new identity field set and its JSON serialization and presence in session files/payloads.
• Update user-facing strings and documentation to accurately describe collected data and opt-out behavior.
