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).

+## OpenContext
+
+[LogicSRC OpenContext](docs/opencontext.md) 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.
+
+> An agent should be replaceable without losing organizational knowledge.

+```bash
+npx opencontext init my-context
+npx opencontext validate --strict
+npx opencontext resolve --role support --task "customer asked for a refund" --explain

+```
+
+Authorization runs before relevance, so an agent never ranks context it may not read; authority is
+declared rather than inferred from retrieval rank; unresolved canonical conflicts are reported
+rather than quietly settled; and resolution is deterministic, so a decision can cite the exact
+bundle digest it was made from. Untrusted content — tickets, chats, scraped pages — keeps its trust
+level through resolution and is fenced and labelled in rendered bundles.
+
+It is not a memory database. Memory is one possible context source; OpenContext is the control
+plane above systems that remain the sources of truth. It runs from a folder and a Git repository
+with no account, no server, and no telemetry.
+
+Also available as `logicsrc context <command>`, sharing one implementation with the standalone
+binary. See the [specification](docs/opencontext/spec.md), [CLI](docs/opencontext/cli.md),
+[SDK](docs/opencontext/sdk.md), [security model](docs/opencontext/security.md), and
+[conformance guide](docs/opencontext/conformance.md).
