AST extractor drops imports_from edges for some source files #414

Summary

graphify extracts AST import edges for some JS/MJS files in a corpus but silently skips them for others, producing misleading degree-0 "orphan" nodes.

Repro

Run /graphify . on a Node.js repo containing:

File A: backend/api/src/seed/run-seed.mjs — 9 explicit relative imports:

import mongoose from "mongoose";
import { CandidateModel } from "../models/candidate.model.mjs";
import { SessionModel } from "../models/session.model.mjs";
import { DecisionModel } from "../models/decision.model.mjs";
import { FeedbackModel } from "../models/feedback.model.mjs";
import { candidateSeeds } from "./prototype/candidates.seed.mjs";
import { sessionSeeds } from "./prototype/sessions.seed.mjs";
import { decisionSeeds } from "./prototype/decisions.seed.mjs";
import { feedbackSeeds } from "./prototype/feedback.seed.mjs";

Observed edges for run-seed.mjs:

• run-seed.mjs --contains--> run() (intra-file)
• runPrototypeSeed() --calls--> run() (intra-file)
• Zero imports_from edges.

All 8 target files exist as nodes in the same graph (they appear in community listings with their own stems), so this isn't a missing-corpus issue.

Counter-example in the same run: backend/api/src/models/enums.mjs is an exports-only file, and the graph correctly shows cross-file edges between it and decision.model.mjs / candidate.model.mjs (resolved via those model files importing ../enums.mjs). So the import resolver handles some ../sibling.mjs cases, just not consistently.

Expected

Each relative import ... from "./foo" or "../foo" statement should produce an imports_from edge whenever the target file is present in the corpus.

Impact

feedback.model.mjs and session.model.mjs appear as degree-0 orphans in GRAPH_REPORT.md despite being actively imported from run-seed.mjs. This inflates the weakly-connected-nodes count and breaks reverse-lookup queries like "which files use session.model.mjs?"

Environment

• graphifyy 0.4.18 (via pipx)
• Python 3.12.3 on Ubuntu-based Linux (kernel 6.17)
• Invocation: /graphify . via the Claude Code skill, default pipeline
• Corpus: 75 files (27 code, 45 docs, 3 images)

Happy to share the full graph.json or construct a minimal repro repo if useful.
