feat(ghidra): configurable import language and analysis seeds (#1667)

* feat(ghidra): configurable import language and analysis seeds

REA_GHIDRA_LANGUAGE_ID and REA_GHIDRA_COMPILER_SPEC_ID set the import
language when the header cannot identify the compiler (for example,
Borland C++ PE images).

REA_GHIDRA_SEED_FILE seeds functions, code and labels before
auto-analysis, for code reached only through computed jumps or data.

Both are validated before launch, recorded in the analysis profile and
verified in the bridge handshake.

* fix(ghidra): parse language XML and preserve seed ordering

* test(ghidra): use explicit platform paths for seed launch checks

* fix(javascript): retain cleanup failure reason in error causes
