feat(archetypes): make magic-wall runes emit restrained red light

[zoeyrose]

Summary

• give every visible magic_wall a persistent radius-1 ff3030 rune-presence cue without coupling light to damage or switch state
• inventory all 57 placements across ten maps and explicitly reconcile all 12 current same-tile emitters
• make same-tile fixture dispositions fail closed, with regression coverage and maintainer guidance

Coordinates

• Base: main at 94eb4d16f7cd46dd4b9a749214e5ae33198b3679
• Head: feat/93-magic-wall-runes-main at 110e6d8719117accfb50d5fe9a0758a09db68c11
• Worktree: workspace/worktrees/content/issue-93-magic-wall-runes-main
• Commits: 462e04352 feat(archetypes): illuminate magic-wall runes; 1d133b8a5 docs(lighting): record magic-wall runtime review; 110e6d871 chore(content): merge latest main into magic-wall work

Validation

• python3 -m unittest tools.tests.test_world_content_audit -v — 4 tests passed
• python3 tools/world_content_audit.py lights --check — 122 archetypes, 10 artifacts, 11,748 instances across 641 maps, zero unreviewed emitters
• python3 tools/validate.py — passed, including 164 tests and catalog/schema/contracts/runtime collection checks
• git diff --check — passed
• isolated Classic profile build — integrated server/client build passed at Classic a10957c86f2df0f7fb66e40830f428f0a45b02cc with the runtime-equivalent magic-wall implementation tree (462e04352; later commits add review evidence and reconcile current-main audit contracts without changing the wall archetype)

Runtime verification

• Profile/scenario/topology: issue-93-magic-wall-runes; scenario state scenario-issue-93-magic-wall-runes; dedicated display :93; topology stopped after review.
• Representative active Plane of Creation walls were compared in smooth and discrete Classic. The radius-1 red cue stayed on the rune surface without flattening adjacent floor, fence, or corner contrast.
• The same positioned 25-wall Underground City stress view was compared in smooth and discrete Classic after resetting the map and exercising its existing 7:10 magic-mouth trigger for connections 102 and 201. The existing INTRUDERS!!! and Security system activated!!! behavior remained intact.
• The dense run did not become a continuous red wash or cross blocked geometry. Walls, water, rooms, and blocked boundaries retained their own contrast.
• Paired views beside co-located wall 7:9 confirmed that the retained radius-9 light9 source still owns the blue room fill; the wall adds only its bounded rune cue, with no second room-scale pool.
• Diagnostic captures remain ignored under build/reviews/; their exact view IDs and conclusions are recorded in maps/light-source-review.json as required by the issue amendment.

Review status

• Source review confirms 57 walls across ten maps: 26 initially active and 31 initially disabled.
• All 12 current same-tile sources are explicitly dispositioned: nine visible crystals, two invisible neutral room-fill helpers, and one visible amber wall torch.
• Independent findings about audit documentation, same-tile identity regression coverage, and missing renderer evidence are fixed and validated.
• Two fresh independent current-base whole-diff reviews found no actionable findings; all latest-head GitHub checks pass.

Closes #93.
