Add TUI conversation management

[harryalbert]

Description

Before this PR, the Warp TUI could resume a conversation only when launched with a server token. There was no way to discover or switch to another local or cloud conversation from the running TUI, and startup restoration could not be cancelled into the provisional new session.

This PR adds a searchable /conversations inline menu backed by the shared normalized conversation model and query policy. It lists eligible personal Oz conversations from local and cloud history, preserves selection across live updates, and revalidates command, conversation, target, and restore state before switching. Successful loads replace the sole TUI transcript through the existing GUI restoration path; failed or cancelled loads leave the current conversation intact. Cloud metadata failures fall back to searchable local history with an explicit warning, and Escape or Ctrl-C can cancel both list and startup restoration without allowing stale completion to replace the active session.

• app/src/ai/agent_conversations_model.rs — partial cloud-metadata failure state exposed to the TUI.
• crates/warp_tui/src/conversation_menu.rs — menu lifecycle, live refresh, query projection, and stable selection.
• crates/warp_tui/src/terminal_session_view.rs — acceptance revalidation, loading/cancellation, and conversation replacement.

Skim

• crates/warp_tui/src/inline_menu.rs and input/view.rs — conversation-specific adapter and accepted-action routing onto the infrastructure from PR 1.

Overview

This PR adds TUI conversation management: a /conversations inline menu, shared conversation query/ranking logic, TUI restore target handling for local/server conversations, cancelable restore state, and supporting specs/tests.

• No security-specific findings were identified.
• The supplied spec_context.md contains no approved or repository spec context; the checked-in CODE-1821 spec in this PR is consistent with the implementation at review depth.
