Correct repo flavor to product; add SCOPE, AGENTS, classification

fix-consistency surfaced that GOAL.md's `repo_flavor: project` was wrong.
project-repository-flavor_v0.1.md reserves the prj- flavor for bounded
cross-repo coordination efforts and says durable products use INTENT.md and an
ordinary category. informed-decision is a durable product, so the C-35
"prj- flavor forbids shipping both INTENT.md and GOAL.md" contradiction was
self-inflicted rather than a real conflict.

- .repo-classification.yaml: category product, domain infotech.
- GOAL.md: drop repo_flavor/project_status, add a flavor note explaining that
  GOAL.md is retained as the stage statement alongside a stable INTENT.md.
- SCOPE.md: honestly empty — states that nothing is implemented and that
  INFD-WP-0001-T06 rewrites it after the gate-house ruling and the specs.
- AGENTS.md: shared State Hub / session / workplan boilerplate, plus the hard
  rules for this repository — never decide, never own approval state, never
  invent identity, never let awareness enter view_hash, never let an agent
  bind, never fork the schema, fail closed.
- INFD-WP-0001: T01 records both corrections; T06 now rewrites SCOPE.md.
