Reorg step 1: consolidate repo under core/, drop the mafiabot label

Mechanical structure-only pass (no document/guide content edits):

- Move src/ichor, src/endocrine, and docs/ into core/; the old top-level
  mafiabot_core/ becomes core/. Everything now lives under a single core/ root.
- Drop the "mafiabot" label from the Ada/Alire crate: core.gpr (project Core),
  alire.toml name = "core"; the generated *_config.* regenerate as core_config.*.
- Repoint build-critical wiring only:
  - .claude/skills/run-sica-fondt/smoke.sh (ponyc + Ada + COBOL paths)
  - core/src/endocrine R source()/runner paths and the test glob
  - .github/workflows/ci.yml (working-directory + gpr name)

Verified green: smoke ALL GREEN (Pony Ichor, Ada core crate + tests, COBOL E1
vault); R endocrine 14/0; Octave ETR 26/0/1.

Deferred (reserved for a less-ephemeral doc/guide pass): docmap.yaml, the guide
files and nested AGENTS.md/README prose + now-stale relative links, SOUL.md, and
the deeper ring/storage restructure.
