PHLEGM v10 r16 — Network FreeBASIC identifier validation fix
Source: r15 Full Archive Set; failure log: Compiler Logs(20261029-025828).zip.

Observed build failure: tools/Validate-FreeBasicIdentifiers.ps1:323 terminated
before the native compiler was invoked. The three fatal findings were:
  src/lib/network-native.bi:21 parameter 'output' is reserved by FreeBASIC -lang fb
  src/lib/network-native.bi:35 parameter 'output' is reserved by FreeBASIC -lang fb
  src/lib/network-native.bi:433 declaration 'output' is reserved by FreeBASIC -lang fb

Fix:
 - Both platform gethostname declarations: output -> hostBuffer.
 - Hex key-bit decoder accumulator: output -> decodedBits, including all references.
 - Revision metadata updated to r16.
 - Added dedicated regression for reserved FreeBASIC networking identifiers.
 - Preserved the in-process FreeBASIC networking architecture (no .NET, C#, or
   PowerShell transport).

Important: These build logs do not contain FreeBASIC native errors, since the
preflight identifier validator rejected r15 before native compilation.
Passing the validator with r16 does NOT establish native compilation success.
