Merge pull request 'Carry project-scope defaults for roles with project management' (#250) from fix/role-project-scope-permissions into main

Why: After the role-authority cutover a role could only carry the single
project.create boolean, so every project-scope action resolved as undefined and
project conversations plus member collaboration were rejected. Owner product
intent: a role carries one project-management toggle, and holding it grants the
in-project defaults (read, write, members, traces, stage, archive, audit);
three-duty and knowledge publishing stay duty-gated.

Evidence: go test ./internal/store ./internal/app ./internal/server -count=1
passes; TestRoleCarriesProjectScopeDefaults covers the write, the snapshot
projection and the unchanged invariant that a role enabling project.create may
not deny a linked management action. The agent-exec transport diff is identical
to the owner-accepted revision deployed on imc-tx-ecs (binary 941f8eef).

Impact: ReplaceRolePermissions accepts project-scope actions while protected
system actions stay refused, RolePermissions projects project-scope rows plus
the project-management implied defaults into the role policy snapshot, and an
explicit capability-association gate runs before each write.
