[Sub-Issue] Implement HAL/S Space Shuttle Signatures

Epic: #75
Target: gitgalaxy/standards/language_standards.py

Context & Strategic Value

With the Apollo Guidance Computer (AGC) assembly already successfully integrated into the engine, GitGalaxy has proven its ability to map extreme embedded edge-cases without an AST. The next critical milestone in our aerospace ontology is HAL/S (High-order Assembly Language/Shuttle).

Developed in the 1970s by Intermetrics for NASA, HAL/S was the primary programming language for the Space Shuttle's onboard flight computers. It is a PL/I dialect that natively supports real-time scheduling and vector/matrix algebra. By mapping HAL/S, we guarantee GitGalaxy can audit the complete spectrum of historical and safety-critical spaceflight software.

Implementation Tasks

• Add hals to LANGUAGE_DEFINITIONS.
• Define Extensions: .hal, .hals.
• Set lexical_family to standard_block (Supports C in the first column for full-line comments, and /* */ for inline block comments).
• Implement structural_boundaries signature: Target PROGRAM, PROCEDURE, FUNCTION, TASK, COMPOOL, and CLOSE.
• Implement concurrency signature: Target real-time OS scheduling primitives (SCHEDULE, WAIT, SIGNAL, PRIORITY, TERMINATE).
• Implement scientific signature: Target built-in math declarations (VECTOR, MATRIX, SCALAR) and arithmetic logic.

Validation

Run the engine against digitized HAL/S Space Shuttle flight control source code or simulator snippets. Ensure the Custom Ontology auto-bins the files into the aerospace domain and the parser correctly extracts the real-time scheduling and orbital math logic.
