Establish Soul Frame research repository and workplans

Scaffold the research layout from the research program, add INTENT/SCOPE,
research instruments, concept stubs, and SOUL-WP-0001–0008 phase workplans.
Register the repo with State Hub under domain agents for hub-synced execution.

+# Being
+
+**Status:** provisional  
+**See also:** `Terminology.md`, RQ1, H1–H2, H7
+
+## Working definition
+
+A **Being** is a sufficiently coherent and persistent informational system that:
+
+1. maintains a distinguishable boundary between itself and its environment,
+2. can be instantiated as an identifiable and addressable entity,
+3. exhibits meaningful continuity across time,
+4. constructs models that support adaptive interaction,
+5. and is recognized by other beings as a persistent counterpart with which
+   relationships can be established.
+
+Beinghood ≈ **internal closure + continuity + external recognition**
+
+## Notes for research
+
+- Not restricted to biological organisms; not automatic for every computational process.
+- Prefer degree of systemic coherence and recognition over a pure binary.
+- Distinguish systemic existence from social recognition of existence.
