codegraph: same-file consumption not recognized by dead code detector

[carlos-alm]

Context

Discovered during Titan audit (phase: gauntlet, date: 2026-04-04).

Description

Constants DEFAULT_WEIGHTS, ROLE_WEIGHTS, DEFAULT_ROLE_WEIGHT in src/graph/classifiers/risk.ts are flagged as dead-leaf despite being consumed by scoreRisk in the same file. The dead code detector does not recognize internal consumption within the same file as "alive".

Impact

Same-file consumers are not tracked, causing constants and helpers used within their own module to appear dead.
