feat(tui): optimistic session creation

Seed new sessions locally with a client-generated session ID and create
them in the background, so submitting from the home screen navigates
into the session and renders the prompt echo immediately. The seed
marks initial reads complete until the session.created echo loads
server truth. Creation failure closes the optimistic tab, returns to
the home screen with the prompt restored, and drops the seed. Worktree-
backed creation and command, skill, and shell submissions keep awaiting
creation.

 - 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.
