PHLEGM v9 - Revision r10 - FreeBASIC namespaced-call compile fix
====================================================================
Base: v9 r9 Regex Record Grammars
Source: PHLEGM-v9-Compiler-Logs-2026-1012-1912-3223.zip

Observed build: 4/4 Windows targets failed (32bit/64bit x OpenGL/D3D11).
Same two diagnostic errors per target, src/lib/definition-parser.bi:
 - r9 line 122, error 42: Variable not declared, get_
 - r9 line 363, error 42: Variable not declared, engine_error

Fix:
 - Resolve aa.get_(captures,offsetKey) into a String local before If Len().
 - Resolve regex.engine_error() into a String local before If Len().
 - No changes to regex.lib, AA/FBVM, record grammar, schema, or machine micro-code.
 - Revision metadata now records revision.current=10 (numeric-only).
 - Added a source guard and a native FreeBASIC r10 regression test.

Validation in packaging environment:
 - Source guard passes; ZIP and checksum integrity verified.
 - No fbc Windows or Linux binary installed here: actual native build NOT verified.
 - The Windows build log fixes are targeted specifically at reported errors.
 - Rebuild all four Windows targets and run AA/Regex native smoke tests.
 - Previous r9 and r8 archives should be retained unchanged.
