Rename the Mind Steward faculty to Life

Operator ruling, 2026-09-25: Epiphany and Aquarium call this organ Life
(role id `reorientation`), and it is "a much better fit as the actual
load-bearing organ". The eureka-site landing page already says Life.

SKILL.md (frontmatter description, faculty table, dispatch lines, step 6,
model allocation), README.md and briefs.md now say Life. The role itself is
unchanged. SKILL.md defers to global doctrine for the agent type, which the
operator owns and which still says mind-steward. Dated records keep the old
name: changelog entries as written, a note on the 2026-09-15 Epiphany
comparison, and "then called Mind Stewards" in the CultCache postmortem.

-description: Eureka runs a foundation change as a faculty pipeline for Claude Code agents. It is the skill counterpart of Epiphany. The root agent acts as Self and routes the work. The target shape is written first, Imagination maps the cut, Hands executes one cut at a time, Soul verifies by trying to falsify what Hands promised, a Mind Steward keeps memory honest at phase boundaries, and the operator rules on real forks. Use it for any migration, rebuild, teardown, cross-repo or cross-runtime change, infrastructure swap, or multi-cut refactor, especially on shared GameCult substrate (CultLib, CultCache, CultNet, CultMesh, CultMath). Also use it when the operator says "Eureka", "map the cut", "Imagination pass", "Soul pass", "Hands", "mini Epiphany loop", or "make this migration look like the last one", or asks to plan and land a change too big for one diff, even without naming the pipeline.
