#1118 — prune stale AST nodes on full re-extraction (#1116)
Stamps every AST-extracted node with _origin="ast" in extract(). On a
full rebuild _rebuild_code drops any AST-marked node absent from the
fresh output even when its source file survives, fixing stale symbols.
Backward-compat: marker-less nodes from pre-1118 graphs survive one
cycle then self-heal.
#1110 — stop reading images and PDFs as garbage in headless extract
Images route through per-backend vision payloads (base64/data-URI/bytes
for claude/openai/bedrock); non-vision backends get _strip_pixels for
graceful degradation. PDFs reuse pypdf. 5MB cap, 20-image chunk limit.
#1159 — Salesforce Apex extractor (.cls, .trigger)
Regex-based extractor: classes, interfaces, enums, methods, triggers,
SOQL/DML edges. No new dependency. Dispatched as .cls and .trigger.
#1107 — Azure OpenAI Service backend (--backend azure)
Uses AzureOpenAI SDK client (from existing openai package). Auto-detects
when AZURE_OPENAI_API_KEY + AZURE_OPENAI_ENDPOINT both set. Uses
max_completion_tokens (not deprecated max_tokens).
#1103 — live PostgreSQL introspection (--postgres DSN)
graphify extract --postgres "postgresql://..." introspects tables, views,
routines, and FK relations via information_schema (SERIALIZABLE READ ONLY).
Credentials sanitized on error. New graphify[postgres] extra (psycopg3).
Union-resolved llm.py conflict: Azure functions + bedrock images= param.
Fixed test_image_vision.py mock to accept timeout= kwarg (our #1112).
