v0.25: cleanup of inline Imperial-Cult references in open papers

Replaces inline iconographic references in the open papers with structural
stubs that describe the cosmology's function in mechanic-vocabulary, while
retaining named-mechanism vocabulary as canonical mechanic-level vocabulary
in the open canon.

EXTRACTED (now living only in closed studio-art repo + the stub +
LICENSING.md's legitimate description of what migrated):
- the named cosmological-iconographic object (the Imperial Wheel)
- source-tradition framing (Bhavachakra; Yama; Yama's seat; capsule-as-Naraka;
  Imperial Yoke; six realms; three poisons)
- doctrinal-split iconography (the orthodox vs heretical wheel split with its
  specific iconographic differentiators)
- aesthetic-vocabulary triad (Boullée + Jantar Mantar + Gita)

RETAINED in open canon as mechanic-level vocabulary:
- the deferred-moksha doctrine (named-mechanism; the binding-lie)
- the unified-clasp framing (imperial-register vs romantic-register)
- the caste-tier-as-mod-status gradient (deva/asura/manusya/tiryak/preta/naraka)
- the no-haven discipline
- the mind-capsule (replacing the iconographic capsule-as-Naraka phrasing)
- the Imperial Cult as Hivemind's ideological apparatus
- "samsara"/"moksha" used metaphorically as cyclic-existence vocabulary

Files edited:
- architecture-index.md: tree-comment + quick-reference table-row + two
  key-moves bullets (Imperial Cult cosmology authored; doctrinal-split
  discovery arc); footer v0.19 -> v0.20.
- README.md: directory-table row for imperial-cult/; footer v0.7 -> v0.8.
- identity-and-personhood/vocations.md: section-heading + diurnal-grammar
  passage in the diurnal-rhythm section.
- identity-and-personhood/bodies.md: lead-paragraph "Imperial Yoke" ->
  "imperial-register clasp" + four cross-reference table-row anchors stripped
  to file-level (acceptable per plan coherence-check; the stub's anchors
  no longer resolve at section-level anyway).
- LICENSING.md: §Migration status pending -> completed; closing paragraph
  updated to reflect that the substrate/content split is now both
  architectural AND inline-coherent.

Files deleted:
- MIGRATION_CLEANUP_PLAN.md (ephemeral scaffold authored at v0.24.5;
  deleted per its own instructions on completion).

Verified via plan §Verification commands: zero remaining iconographic
references in any open paper outside LICENSING.md (which legitimately
describes what migrated) and the stub at imperial-cult/cosmology.md.

Closes the migration cycle initiated in v0.22 (licensing-marker), v0.24
(cosmology.md -> stub), and the inaugural commit of
studio.nimmerworld.eachpath.local (canonical home). The substrate/content
split is now fully physical AND fully reflected in the open papers'
inline-vocabulary.

 **Completed 2026-04-27**: `imperial-cult/cosmology.md` has migrated to the closed studio-art repository at [`git.eachpath.com/nimmerverse/studio.nimmerworld.eachpath.local`](https://git.eachpath.com/nimmerverse/studio.nimmerworld.eachpath.local). A stub file remains at `imperial-cult/cosmology.md` in this open repository, preserving cross-reference discoverability and pointing at the canonical home.
 
-**Pending — follow-up editorial cleanup**: References to specific Imperial-Cult iconography (the Imperial Wheel; the Bhavachakra-rework; the orthodox/heretical split; the deferred-moksha doctrine; the specific aesthetic vocabulary of Boullée + Jantar Mantar + Gita) currently appear inline in several open papers (`architecture-index.md`, `bodies.md`, parts of `political-register/architecture.md`). These will be replaced in a follow-up editorial pass with structural stubs that describe the cosmology's *function* in mechanic-vocabulary without revealing the specific iconographic content (e.g., *"the Imperial Cult cosmology — see studio docs for canonical iconography"*).
+**Completed 2026-04-27 (same-day continuing)**: Inline references to specific Imperial-Cult iconography (the named cosmological-iconographic object; the source-tradition framing; the doctrinal-split iconography; the aesthetic-vocabulary triad) have been replaced across the open papers (`architecture-index.md`, `README.md`, `identity-and-personhood/vocations.md`, `identity-and-personhood/bodies.md`) with structural stubs that describe the cosmology's *function* in mechanic-vocabulary. Named-mechanism references (the deferred-moksha doctrine; the unified-clasp framing; the caste-tier-as-mod-status gradient; the no-haven discipline) are retained as canonical mechanic-level vocabulary in the open canon, with cross-references that resolve at file-level to the stub.
 
-The boundary EXISTS architecturally; the inline-reference cleanup is editorial work that can happen at leisure without licensing-ambiguity growing — the licensing-marker + per-file headers + closed-repo migration together establish the boundary even before the inline cleanup is finished.
+The substrate/content split is now both architectural AND inline-coherent in the open papers. The migration cycle (v0.22 licensing-marker → v0.24 cosmology.md → stub → v0.25 inline cleanup) closes.
