Scan all project dependencies for known vulnerabilities using Software Composition Analysis. Use when the user says "scan my dependencies", "SCA scan", "vulnerable dependencies", "endor sca", "what's wrong with my deps", or wants a focused dependency vulnerability report with direct vs transitive breakdown. Do NOT use for checking a single package (/endor-check), SAST code scanning (/endor-sast), or quick full scan (/endor-scan).
