refactor(simulation): strip archetype trace + HeritageRoot per cascade (#877, #878)

Sprint 37 dead-code sweep closing out two stale supersession chains:

#877 (D-167, 2026-03-24): Removes HeritageRoot type alias and
ZonePaletteModifier::Heritage variant from server/src/simulation/
generator.rs. The 7 abstract heritage roots were retired in favour of
the corridor cultural system; these two stubs were the only remaining
references.

#878 (D-032 + cascade rule): Strips the entire CharacterArchetype
(Smuggler/Detective) trace from the server. Per lead direction
2026-04-21 and the development cascade (CLAUDE.md), character/NPC/
verb-differentiation/monologue code is Phase 6 detail that should
not exist in code yet. The running archetype trace was pre-cascade
filler, not production — production is only the client's character-
creation UI and insert screens (client follow-up in #882).

Deleted:
- CharacterArchetype enum + StartupMessage.character_archetype field
- archetype_verb_label() + archetype branch of apply_phase2_verb_filter
  (D-057 character-verb differentiation — marked superseded)
- MonologueState.character partitioning
- Gauntlet archetype plumbing (setup_gauntlet no longer takes an archetype)
- server/content/schemas/drama_module.schema.yaml (zero Rust consumers)
- server/content/modules/tier1/smuggling_ring_v0_1.yaml
- server/tests/archetype_monologue.rs (regression guard for the removed system)
- server/tests/v01_integration_playthrough.rs (archetype-dependent)

Decision updates:
- decisions/content.md D-032 supersession rewritten to cite the cascade
  (v0.2 drop invalidated the prior D-117 framing).
- decisions/content.md D-035 tag taxonomy: `character` enum footnote
  updated; field noted as unused, do not reintroduce without a
  confirmed Phase 6 design.
- decisions/perception.md D-057: archetype-verb differentiation marked
  superseded.

Also bundles the types.rs version-field removal from #874 since the
file was already touched here.

+- **Supersession note (2026-04-21, Sprint 37, #878):** The character-archetype verb variation portion of this decision is superseded by the development cascade (CLAUDE.md) — archetype-driven verb relabeling is Phase 6 detail-coloring and has been stripped from the server. Vertical-list structure, Phase 1/Phase 2 split, POI priority flips, and contradiction markers remain live. Relabeling (Open→"Move"/"Stash" vs "Scan"/"Flag") is deleted; verbs now render with their base labels regardless of character.
 - **Decision:** Entity interactions use a compact vertical list (not radial). 2-4 options max, anchored to entity position. Insert-styled with Araminta's geometric aesthetic. New options unlocked by knowledge changes are highlighted with a gradient glow background. Radial menu reserved for world menu only ([D-058](#d-058-world-menu--radial-4-spokes)). Max 3 visible response options in dialogue context.
-- **Server architecture:** Two-phase verb computation. Phase 1 (simulation, no KG): compute maximum possible verb set from ObjectType component (Readable, Container, Terminal, Door, Pickup, Furniture — each with specific verb sets). Phase 2 (observer, reads KG): filter by character's knowledge (Confront requires KnowsDetails+ per [D-041](architecture.md#d-041-knowledge-graph-data-model)), apply POI priority flips, add contradiction markers. Character-archetype verb variation implemented as Phase 2 observer filter rules (same crate: smuggler sees "Move/Stash", detective sees "Scan/Flag").

 - **Diegetic test:** Labels render on z-layer 6. If insert is off, labels disappear.
 - **Rationale:** Variable-length text options (e.g., confrontation lines in character voice) break radial spatial memory. List handles 1-4 options cleanly. New-item glow signals "something changed" without UX hazard of geometry transforming under cursor. Two-phase computation enables character differentiation without separate verb systems.
