refactor: Cut dead code paths (#438)

## Summary

- remove the legacy debug-only `/rollout` and `/test-approval` slash
commands from the TUI command surface and their dead handlers/tests
- trim compatibility-only `login_status` and `auth_manager` fields from
the Nori onboarding args so the Nori path only carries live data
- delete the orphaned top-level update modules and stale snapshot, and
refresh `codex-rs/tui/docs.md` so it documents the Nori update path that
actually ships in `nori`

## Why

This PR is a dead-code cleanup pass focused on the ACP-backed Nori CLI.
It removes compatibility baggage and uncompiled upstream leftovers from
`nori-tui`, which keeps the branch net-negative and reduces accidental
complexity in the code that matters for the `nori` binary.

## Validation

- `RUSTC_WRAPPER= cargo test -p nori-tui --manifest-path
codex-rs/Cargo.toml`
- `RUSTC_WRAPPER= cargo build --bin nori --manifest-path
codex-rs/Cargo.toml`
- `RUSTC_WRAPPER= cargo test -p tui-pty-e2e --manifest-path
codex-rs/Cargo.toml`
- `RUSTC_WRAPPER= just fix -p nori-tui`
- `just fmt`
- launched `./target/debug/nori --agent elizacp --skip-trust-directory`
in an isolated tmux session, submitted `hello`, observed an ElizACP
reply, and verified the prompt returned

-The `Ask` popup is implemented by `nori::worktree_ask::run_worktree_ask_popup()`, a standalone mini-app screen (same pattern as `update_prompt.rs`) that runs its own event loop before the main `App`.

 **Session context injection:** Both `spawn_acp_agent()` and `spawn_acp_agent_resume()` in `chatwidget/agent.rs` set `AcpBackendConfig.session_context` to the contents of `@/codex-rs/tui/session_context.md` (loaded at compile time via `include_str!`). This tells the ACP agent that it is running inside the nori CLI and provides a source-code URL for self-referential questions. The context is prepended (without `SUMMARY_PREFIX` framing) to the first user prompt only and then consumed (see `@/codex-rs/acp/docs.md` for the hook context injection mechanism).
