Ambient-agent ODRL policy shape

Validates odrl:Policy instances intended for bra0 ambient agents per arch-delta §3.1.1. Only targets policies carrying evo:agentRoleProfile (P0-4 fix: SPARQL target replaces sh:targetClass to avoid over-matching on non-ambient policies). Every ambient policy MUST declare a role profile (Reader/Writer/Trigger) and an enforceable bounded context. Q10 resolves at W06; shape works with partial resolution (Reader role only) for v0.8 narrow-first E7 ship.

Target class: ---

Property path	Constraint	Cardinality
dcterms:identifier	xsd:string · 1	1..odrl:Policy MUST carry dcterms:identifier (policy IRI slug).
odrl:permission	1 · odrl:Policy MUST carry ≥1 odrl:permission (at least one explicit permitted action).	—
odrl:prohibition	0 · odrl:Policy MAY carry odrl:prohibition (explicit prohibitions beyond Reader/Writer/Trigger defaults).	—
evo:agentRoleProfile	xsd:string · 1	1..odrl:Policy for an ambient agent MUST declare evo:agentRoleProfile ∈ {Reader, Writer, Trigger} per arch-delta §3.1.1 (v0.8 narrow-first allows Reader only; WRITE/TRIGGER accept at v0.9 post-Q10).
evo:declaredContext	sh:IRI · 1	odrl:Policy MUST declare evo:declaredContext pointing at a named-graph IRI (bounded context — arch-delta v0.1.4 §3.2.2 predicate)...*
