V37 Gate 6: Conversation Terminal handoff

Adds the package-owned ConversationTerminalHandoff contract, generated source-safe artifact, protocol exports, checker, and package tests.

Wires Conversations to prepare source-safe Terminal handoff envelopes and Terminal to read handoff route context while preserving ledger, wallet, settlement, delivery, and BTD authority boundaries in Terminal.

Updates V37 specification documents, roadmap, READMEs, workflows, targeted Jest coverage, and local validation scripts for Gate 6 closure.

+## V37 Gate 6 ConversationTerminalHandoff canon
+
+Gate 6 implements `ConversationTerminalHandoff` as the package-owned
+transaction handoff contract from Website Conversations into the Bitcode
+Terminal. It owns source-safe handoff envelopes for Depositing, Reading,
+Finding Fits, Exchange, settlement, and delivery workflows. It emits
+`.bitcode/v37-conversation-terminal-handoff.json` with
+`source-safe-conversation-terminal-handoff-metadata`, deterministic row roots,
+deterministic detail roots, workflow ids, field ids, authority boundary ids,
+policy states, proof roots, event ids, source evidence roots, and source-safe
+disclosure limits.
+
+Conversation handoff is not execution. Conversations may prepare source-safe
+transaction intent, preserve a route-local conversation id, selected
+transaction id, repository anchor, source selector summaries, a user-readable
+summary, policy result, proof root, and Terminal detail focus. The Terminal
+remains the transaction cockpit and the only website surface that may proceed
+into ledger, wallet, settlement, Exchange, delivery, and BTD ownership actions.
+Conversation handoff payloads must not expose protected source, raw protected
+prompts, protected model responses with source, provider tokens, wallet
+private material, settlement private payloads, unpaid AssetPack source, ledger
+write authority, wallet signing authority, or a Terminal authority bypass.
+
+The Terminal route reads `conversationHandoff=1` context as source-safe
+operator context. It may display the workflow, policy state, proof root,
+repository anchor, source selector count, and handoff summary before the
+operator chooses any Terminal action. `check:v37-gate6` validates package
+source, generated artifact freshness, package tests, UI tests, Terminal route
+tests, docs, workflow wiring, workflow coverage, authority boundaries,
+proof roots, event ids, and source-safe handoff metadata.

+## Gate 6 implementation notes
+
+ConversationTerminalHandoff contracts are source-safe transaction-intent
+contracts, not Terminal execution, ledger writes, or wallet signing. Gate 6
+adds `.bitcode/v37-conversation-terminal-handoff.json`,
+`buildConversationTerminalHandoff`, the route-facing handoff helper, the
+handoff component, Terminal route context parsing, package tests, UI tests,
+Terminal route tests, and `check:v37-gate6`.
+
+The required workflows are Depositing, Reading, Finding Fits, Exchange,
+settlement, and delivery. Handoff envelopes may carry conversation id,
+transaction id, repository anchor, source selector summaries, a source-safe
+summary, policy result, Terminal route, transaction detail, proof root, and
+event id. They must not carry protected source, raw protected prompts,
+protected model responses with source, provider tokens, wallet private
+material, settlement private payloads, unpaid AssetPack source, ledger write
+authority, wallet signing authority, or a Terminal authority bypass. The
+Terminal remains the transaction cockpit.
