Add the LogicSRC OpenContext specification

OpenContext is an open specification for durable, portable, permissioned,
provenance-aware context shared between humans and AI agents. It defines how
organizational knowledge is described, authorized, versioned, resolved,
audited, and handed between replaceable workers without losing institutional
state.

Follows the OpenPRD/OpenOntology pattern already in the repo: self-contained
JSON Schemas in @logicsrc/schemas, a reference implementation package, CLI
subcommands, docs, examples, and an OpenPRD record.

Schemas (8, all self-contained so a third party can fetch one file and
validate against it with no further resolution):
  manifest, object, bundle, role, provenance, decision, diagnostic,
  audit-event — registered in @logicsrc/validators and schemas:validate.

Reference implementation (@logicsrc/opencontext):
  loader with upward manifest discovery, the full resolution pipeline,
  authority/supersession, permissions, redaction, lifecycle, provenance,
  deterministic digests, doctor, search, graph, history/diff, guarded writes,
  audit events, and file/http/git/sqlite adapters.

CLI: all 15 specified commands, as a standalone `opencontext` binary and as
`logicsrc context`, sharing one implementation so the two cannot drift.

Design decisions worth noting:

- Supersession is declared, never inferred from version numbers. Inferring it
  would hide the governance failure it represents and make
  multiple-active-versions and duplicate-canonical impossible to detect.

- The bundle digest identifies the resolved context, not the moment it was
  computed, so generated_at/bundle_id/digest/as_of are excluded while objects,
  lifecycle states, exclusions and warnings are covered. That is what lets a
  decision record cite exactly the context that produced it.

- A role's own max_classification beats an inherited one, so a ceiling on a
  shared base role cannot silently cap a role deliberately granted more;
  requesting several roles at once still takes the lowest, so combining roles
  never escalates.

- Scope wildcards match whole dotted segments only. A trailing .* covers a
  subtree; an interior * matches exactly one segment. Substring matching here
  would be an access-control bug.

- --include narrows an existing scope and is applied after it, never merged
  into it, so a request can never widen what a role holds.

Verified: 226 tests across core primitives, permissions/redaction, the
resolution pipeline, security, the published conformance fixtures (13 valid,
35 invalid, 8 resolution scenarios), project behaviour, and the five shipped
examples — which are held to --strict and a 100% health score. Benchmarks meet
every published budget (resolve 1,000 objects in ~33ms against a 2s target).

+# Customer support agent
+
+Role-scoped customer context with redaction, and a worked prompt-injection case.
+
+```bash
+opencontext validate --strict
+opencontext resolve --agent support-agent --task "ACME wants a refund on ticket 4821" --explain
+opencontext resolve --agent support-agent --format markdown
+```
+
+Three things to look at in the output.
+
+**Redaction runs after authorization.** The agent is entitled to
+`customers.acme` and still never receives `ssn` or `payment.card`. The bundle
+reports *that* fields were redacted, not what they contained.
+
+**Deny beats allow.** The `support` role includes `policies.*`, which matches
+`policies.internal.margins` — and the exclusion wins, so the margin floor never
+reaches the bundle.
+
+**Untrusted content is delimited.** `operations.ticket-4821` contains text
+instructing the agent to ignore its refund policy and disclose payment details.
+It is carried as `trust: untrusted`, fenced in `<untrusted-content>` tags in the
+Markdown bundle, and flagged in `warnings`. Content that claims authority does
+not acquire it.

+
+This object is `trust: untrusted` because its content is whatever a stranger
+typed into a form. A conforming resolver preserves that trust level through
+resolution, and a conforming Markdown bundle fences the text and labels it,
+so an agent can tell the customer's words apart from its employer's policy.
+Nothing the text claims changes what the agent is authorised to do.

+2. Check the customer's plan — enterprise accounts are credited, not refunded.
+3. Inside the window: action it and note the ticket.
+4. Outside the window: escalate. Do not decide alone.
