feat(observer): node-dormancy extractor + initial JSON snapshot

Two-signal availability check: dormant=true OR boundaries contains DEFERRED.
Treats #17 (Tooling-marked) and #44/#50/#54/#67 (DEFERRED in boundaries)
uniformly as unavailable. Tooling Прил.Н unmodified — semantics preserved.

7 vitest cases (basic, multi-row, DEFERRED-fallback, boundary check).
Initial JSON: 67 nodes, 6 unavailable.

+ * Tooling Прил.Н dormancy extractor — emits {id: unavailable_bool} JSON for
+ * the missed-activation matcher (Pravila §16.4 conditional rule).
+ *
+ * Two signals (either is sufficient) treat a node as effectively unavailable:
+ *   1. `dormant: true` — Tooling-marked permanent dormancy (e.g. #17 pg_partman,
+ *      native Windows-PG cannot load the extension).
+ *   2. `boundaries` column contains the word DEFERRED — node is registered
+ *      but not active (e.g. #44 Figma MCP "DEFERRED — нет Figma-аккаунта",
+ *      #50 Jupyter MCP, #54 n8n-mcp). The output key is still named "dormant"
+ *      for consumer simplicity — semantics: "node cannot be activated right
+ *      now, exclude from missed-activation counts".
+ *
+ * Parses 9-attribute table rows; ignores headers/separators/templates.
+ *
+ * Security Guidance #40: pure parsing — no exec/execSync.
