evandance 2b4c6349a1 feat(event): emit typed error envelopes across the event domain (#1289)
Replace every command-facing error path in the event domain — the
consume/schema command layer, the +subscribe shortcut, EventKey
definitions, and the consume orchestration — with typed errs.*
envelopes, so consumers get stable type, subtype, param, hint, and
missing_scopes metadata for classification and recovery instead of
free-form message text.

- Input validation (--jq, --param, --output-dir, --filter, --route,
  unknown EventKey, EventKey params) reports validation /
  invalid_argument with the offending flag in param and an actionable
  hint.
- Scope preflight reports authorization / missing_scope with the
  machine-readable missing_scopes list; console-subscription and
  single-bus preconditions report failed_precondition with recovery
  hints.
- The consume API boundary passes already-typed errors through and
  classifies transport, non-JSON HTTP, and unparsable responses; the
  vc note-detail retry now matches the not-found code on typed errors
  (it silently never fired against the legacy envelope shape).
- Previously-bare failures exited 1 with a plain-text "Error:" line
  and now exit with their category code (validation 2, auth 3,
  network 4, internal 5) alongside the typed stderr envelope.
- forbidigo and errscontract guards now cover the event paths so
  regressions fail lint; AGENTS.md and the lark-event skill document
  the typed contract for agent consumers.

Validation: make unit-test (race) green; event unit and e2e suites
assert category/subtype/param/hint and cause preservation against the
real binary; errscontract and golangci lint clean.
