fix(ios): pass log message as NSLog argument, not format string

[bkuhl]

Problem

PHPSchemeHandler.getResponse(request:completion:) interpolates the request URI directly into NSLog's first argument:

NSLog("[NativePHP] [\(mode)] --> \(request.method) \(request.uri)")

NSLog's first argument is a printf-style format string. Swift string interpolation embeds the URI into that format string verbatim, so any % in the URI is parsed as a format specifier. When the URI contains %XX percent-encoded sequences (the normal case for any path with reserved characters or rawurlencoded data), NSLog reads va_args that don't exist and dereferences garbage memory.

Result: EXC_BAD_ACCESS (SIGSEGV) on the com.nativephp.persistent-php queue. Reproducible whenever a request's URI contains %. Stack trace top frames:

__CFStringAppendFormatCore

_os_log_with_args_impl
_NSLogv
specialized withVaList<A>(_:_:)
closure #1 in PHPSchemeHandler.getResponse(request:completion:)  PHPSchemeHandler.swift:595

Fix

Use NSLog's two-argument form so the message is an argument to %@, not part of the format string. Two-line change to lines 595 and 609:

-NSLog("[NativePHP] [\(mode)] --> \(request.method) \(request.uri)")
+NSLog("%@", "[NativePHP] [\(mode)] --> \(request.method) \(request.uri)")

-NSLog("[NativePHP] [\(mode)] <-- \(statusLine) (\(String(format: "%.1f", elapsed))ms)")
+NSLog("%@", "[NativePHP] [\(mode)] <-- \(statusLine) (\(String(format: "%.1f", elapsed))ms)")

Identical log output, no crash. Same pattern any printf-style API expects: format string is a constant; data goes through arguments.

Test plan

• Reproduced crash on simulator with a URI containing %XX sequences (real-world rawurlencode'd token)
• After fix: same URI, no crash, identical log output
• URIs without % (the only ones that didn't crash before) still log correctly
