Add privileged legal matter bootstrap intent/executor #147

Linked canonical initiative: chittyos/chittycounsel#6.

Objective

Project the standardized legal matter bootstrap into ChittyCommand's existing durable intent/executor ladder. Do not create a new workflow service or persistence model.

Runtime findings

• ChittyCommand is deployed and owns cc_intents, executor registry, sovereignty, retries/reclaim, Durable Objects, triage queues, legal timeline and litigation routes.
• ChittyFlow is not deployed and its repo/runtime drift makes it unsuitable as the current orchestrator.

First slice

Add intent_type legal_matter_bootstrap:

• payload requires case_chitty_id
• classified privileged + legalink
• executor is read-only
• executor queries ChittyCounsel GET /case/:chitty_id/bootstrap
• response is written only through existing cc_actions_log by dispatcher
• no new schema/tables
• no evidence/fact mutations
• no external transmission

Acceptance

• registered in meta/executors/index.ts
• payload validated
• upstream timeout/error is fail-closed
• case id is URL encoded
• bootstrap response provenance preserved
• unit tests for success, validation failure, and upstream failure
• typecheck/tests pass
• docs updated only for executor registry/API behavior actually implemented

Deployment remains a separate approval boundary.
