chore(meta): docs/build sweep + tooling test gate (T-1069, T-1066)

- make test-tooling: planet-gen determinism guard + import_economics
  --dry-run, wired into pre-push on TOOLING_CHANGED; ruff widened to
  E4/E7/E9/F/W (90 safe auto-fixes applied; E402/E702/F841 ignored with
  documented counts)
- one-generator reality fixed in DEVOPS.md, asset-pipeline rule, CLAUDE.md
  (import_economics sole generator since #951/D-223); dead check-protocol
  target deleted; DEVOPS hook/config sections rewritten from the actual
  hook sources; team-patterns gate description updated (client+tooling)
- project.yaml: 0.2.0 → 0.4.0 per the 0.{phase}.{n} scheme, description
  refreshed from the v0.1 Sova narration to cascade reality
- stale comment sweep: voxel.rs stub claims (all 8 families implemented),
  cascade.rs TODO recited to T-1044, main.rs D-192 handshake claim,
  relationships.rs/chunk_streaming.rs version targets → phase language
- gitignore: client/settings.db* e2e-run artifacts

 description: >
-  Top-down immersive sim with occlusion-based detection mechanics and
-  combat elements. Single-character perspective where asymmetric information
-  is the core gameplay mechanic. A Rimworld-style storyteller drives
-  emergent narrative across a detective-smuggler dual-lens campaign.
+  Top-down life-sim set in an original science fiction universe. Asymmetric
+  information and occlusion-based perception from a single-character
+  perspective, with a Rimworld-style storyteller. Systems interactions like
+  The Sims, combat and visuals like single-character Rimworld, world
+  generation inheriting from Dwarf Fortress and NMS, economy inspired by
+  X4/EVE. Every system is interactable but ignorable — the world is alive
+  for any given run.
 
 setting: >
-  Original science fiction universe — the Settled Reach, a network of
-  star systems connected by Founder Gates. Neural lattice technology
-  enables soft immortality, forking, and re-embodiment. The v0.1
-  vertical slice takes place in Sova Transit District, Van Maanen's Star.

+development: >
+  Built outside-in along the six-phase Development Cascade (D-166): wiki
+  content and star map, economics layer, planetary maps and atlas,
+  deterministic world generation (active), player control and in-world
+  rendering, room-level detail.
