HTML file parsing for script, stylesheet, and Angular template references.
Extracts <script src="..."> and <link rel="stylesheet" href="..."> references
from HTML files, creating graph edges so that referenced JS/CSS assets (and their
transitive imports) are reachable from the HTML entry point.
Also scans for Angular template syntax ({{ }}, [prop], (event), @if, etc.)
and stores referenced identifiers as MemberAccess entries with a sentinel object,
enabling the analysis phase to credit component class members used in external templates.
