[log] middleware: add debug logging calls to jqschema

[github-actions]

Summary

Adds logMiddleware.Printf debug logging calls to internal/middleware/jqschema.go.

The logMiddleware logger was declared (var logMiddleware = logger.New("middleware:jqschema")) but never used. This PR activates it with 4 meaningful logging calls:

Changes

• WrapToolHandler – logs when a tool handler is wrapped with the middleware, including toolName, sizeThreshold, baseDir, and whether a pathPrefix is set
• applyJqSchema (entry) – logs the start of schema inference with the Go type of the input data
• applyJqSchema (exit) – logs successful schema inference with the result type
• ShouldApplyMiddleware – logs the apply/skip decision for each tool

Why this matters

The existing operational logging uses logger.LogInfo/LogDebug (written to files). The logMiddleware calls provide developer-facing trace output enabled only when DEBUG=middleware:* is set, following the pattern used throughout the codebase.

Testing

• All unit tests pass: go test ./internal/middleware/...
• No new imports required (logger package already imported)
• No side effects in log arguments

Changes:

• Add debug logging at the start/end of applyJqSchema to capture schema inference lifecycle and types.
• Add debug logging when wrapping tool handlers (WrapToolHandler) with configuration details.
• Add debug logging to ShouldApplyMiddleware to record apply/skip decisions.

PR description says logMiddleware was declared but never used, but this file already contains an existing logMiddleware.Printf("Applied default timeout...") call. Please update the PR description to reflect that the logger was already used (this PR adds additional debug lines rather than first usage).

Updated the PR description to reflect that logMiddleware was already in use (existing Applied default timeout call at line 182) — this PR adds additional debug lines rather than being the first usage.
