feat(tui): optimistic prompt submission

Echo user prompts into the local data store with a client-generated
message ID before server admission. The editor clears and the message
renders immediately; admission runs in a per-session background queue
that preserves steer order. The session.inbox.enqueued echo replaces
the local copy with server truth, wholesale sync replaces re-append
unconfirmed echoes, and failures roll back the echo, restore the
captured prompt, and toast.

 - Run `bun run dev:live` from a development worktree to test its TUI against the currently elected `opencode2` background server and live sessions.
 - Pass a directory after the script when needed, for example `bun run dev:live /path/to/project`.
-- The script discovers the server with `opencode2 service status`, injects its private local credential from `opencode2 service get password`, and uses the `dev` TUI storage channel so tabs and other client-local state match the installed client.
+- The script discovers the server with `opencode2 service status`, injects its private local credential from `opencode2 service get password`, and uses the `next` TUI storage channel so tabs and other client-local state match the installed client.
 - Prefer `dev:live` over plain `bun run dev` for this workflow. An implicit managed-service connection may replace the live server when the worktree client version differs; explicit `--server` warns and continues without replacing it.

-## [MCP servers](https://opencode.ai/v2/docs/mcp-servers)
-
-Configure MCP servers under `mcp.servers`. Prefer the CLI because it preserves
-unrelated configuration. Use `--global` when the user asks to set up a service
-for themselves without limiting it to the current project; omit it when they
-explicitly want project-local configuration.
-
-```sh
-opencode2 mcp add <name> --global --url <remote-url>
-opencode2 mcp list
-```
-
-Remote servers use OAuth by default. If `mcp list` reports that a server needs
-authentication, run the OAuth flow and then verify the connection:
-
-```sh
-opencode2 mcp auth <name>
-opencode2 mcp list
-```
-
-The auth command prints an authorization URL, waits for the browser redirect,
-and stores credentials outside the OpenCode configuration. Do not ask for or
-store an API key when the server supports OAuth. Use header-based credentials
-only when OAuth is unavailable or the user explicitly requires them, and use an
-environment substitution such as `{env:MCP_API_KEY}` instead of writing a
-secret into configuration.

 ## [V1 to V2 migration](https://opencode.ai/v2/docs/migrate-v1)
 
 For any request to migrate OpenCode configuration, agents, commands, skills,
 plugins, integrations, or other behavior from V1 to V2, read the full
