feat: #[onto_mcp_tool] catalog, OCI credential vault layer, validate ADR-018 mode hierarchy
ontoref-derive: #[onto_mcp_tool] attribute macro registers MCP tool unit-structs in
  the catalog at link time via inventory::submit!; annotated item is emitted unchanged,
  ToolBase/AsyncTool impls stay on the struct. All 34 tools migrated from manual wiring
  (net +5: ontoref_list_projects, ontoref_search, ontoref_describe,
  ontoref_list_ontology_extensions, ontoref_get_ontology_extension).

  validate modes (ADR-018): reads level_hierarchy from workflow.ncl and checks every
  .ncl mode for level declared, strategy declared, delegate chain coherent, compose
  extends valid. mode resolve <id> shows which hierarchy level handles a mode and why.
  --self-test generates synthetic fixtures in a temp dir for CI smoke-testing.

  validate run-cargo: two-step Cargo.toml resolution — workspace layout first
  (crates/<check.crate>/Cargo.toml), single-crate fallback by package name or repo
  basename. Lets the same ADR constraint shape apply to workspace and single-crate repos.

  ontology/schemas/manifest.ncl: registry_topology_type contract — multi-registry
  coordination, push targets, participant scopes, per-namespace capability.

  reflection/requirements/base.ncl: oras ≥1.2.0, cosign ≥2.0.0, sops ≥3.9.0, age
  ≥1.1.0, restic declared as Hard/Soft requirements with version_min, check_cmd, and
  install_hint (ADR-017 toolchain surface).

  ADR-019: per-file recipient routing for tenant isolation without multi-vault. Schema
  additions: sops.recipient_groups + sops.recipient_rules in ontoref-project.ncl.
  secrets-bootstrap generates .sops.yaml from project.ncl in declarative mode. Three
  new secrets-audit checks: recipient-routing-coherent, recipient-routing-coverage,
  no-multi-vault. Adoption templates: single-team/, multi-tenant/, agent-first/.
  Integration templates: domain-producer/, mode-producer/, mode-consumer/.

  UI: project_picker surfaces registry badge (⟳ participant) and vault badge
  (⛁ vault_id · N, green=declarative / amber=legacy) per project card. Expanded panel
  adds collapsible Registry section with namespace, endpoint, and push/pull capability.
  manage.html gains Runtime Services card — MCP and GraphQL toggleable without restart
  via HTMX POST /ui/manage/services/{service}/toggle.

  describe.nu: capabilities JSON includes registry_topology and vault_state per project.
  sync.nu: drift check extended to detect //! absence on newly registered crates.
  qa.ncl: six entries — credential-vault-best-practice (layered data-flow diagram),
  credential-vault-templates (paths A/B/C), credential-vault-troubleshooting (15 named
  errors), integration-what-and-why (ADR-042 OCI federation), integration-how-to-implement,

## Level hierarchy and mode resolution strategy (migration 0017)
Implements ADR-018: three-level hierarchy with per-mode resolution strategy.
This makes domain boundaries explicit and mode traversal observable.
### Step 1 — Declare level identity in .ontology/manifest.ncl
Inside the manifest record, add a `level` field. The value depends on what
this project IS in the hierarchy:
# Level 2 — project domain (e.g. provisioning, personal):
level = {
index = 'Domain,
name = \"<your-domain-name>\", # e.g. \"provisioning-domain\"
parent = \"ontoref-base\",
},
# Level 3 — domain instance (e.g. a concrete workspace or infra project):
level = {
index = 'Instance,
name = \"<your-instance-name>\", # e.g. \"myorg-provisioning\"
parent = \"provisioning-domain\", # matches the domain's level.name
},
ontoref itself declares no level field — 'Base is the implicit default.
### Step 2 — Add strategy to reflection modes in reflection/modes/*.ncl
Each mode at level 2+ must declare how it relates to the parent level's mode.
# Mode is fully implemented here — traversal stops:
strategy = 'Override,
# Mode is not implemented here — traverse to parent for execution:
strategy = 'Delegate,
# Mode accumulates contributions from all levels (lower level wins conflicts):
strategy = 'Merge,
# Mode inherits specific steps from the parent, overrides the rest:
strategy = 'Compose,
extends = [\"step-id-from-parent\", \"other-step-id\"],
Implicit absence (no strategy field at level 2+) is treated as 'Delegate with
a Soft validation warning from ore validate modes --check strategy-declared.
### Step 3 — Verify (once ore validate modes is available)
ore validate modes --check level-declared
ore validate modes --check strategy-declared
ore validate modes --check delegate-chain
### Step 4 — For strategy transitions: bind to state.ncl
When a mode's strategy is expected to change as the project matures, declare
a dimension in state.ncl. Example — a mode currently delegating that will
eventually override:
{
id = \"build-docs-strategy\",
description = \"build-docs mode resolution strategy: Delegate → Override\",
current_state = \"Delegate\",
desired_state = \"Override\",
catalyst = \"implement project-specific doc generation\",
blocker = \"doc generation not yet implemented for this domain\",
},
When the implementation is complete: update current_state = \"Override\" in state.ncl
AND update strategy = 'Override in the mode NCL. This makes the transition an
observable FSM event (tracked in git, visible via ore describe state).
