refactor(neovim): switch CodeCompanion adapter from gemini_cli to codex_acp

Browse Source 
Reuses the codex CLI's ChatGPT login (auth_method = "chat-gpt") instead of
gemini's oauth-personal, and disables adapter preset noise in the picker.

# Verified against https://codecompanion.olimorris.dev/configuration/adapters-acp
# (CodeCompanion >= v18.0.0, which is what's pinned by nixvim's nixpkgs as of
# 2026-08). Two things changed from an older/assumed layout:
# - the default-adapter key is `interactions.chat.adapter`, not
# `strategies.chat.adapter` (renamed in v18.0.0);
# - the built-in adapter names are `claude_code` and `gemini_cli` (no
# `_acp` suffix) and live under `adapters.acp.<name>`.
# - the built-in adapter name is `claude_code` (no `_acp` suffix) and
# lives under `adapters.acp.<name>`.
#
# Neither adapter has a true zero-config mode that silently piggybacks on
# an already-logged-in CLI session:
# - gemini_cli: `defaults.auth_method = "oauth-personal"` reuses the
# `gemini` CLI's own login — no key needed, closest thing to "just
# use my existing session".
# - codex_acp: extends the built-in `codex` preset. `defaults.auth_method`
# accepts "api-key" | "chat-gpt" (confirmed against the docs above,
# not "chatgpt"/"openai-api-key"/"codex-api-key"). "chat-gpt" reuses
# your ChatGPT/Codex CLI login instead of an OPENAI_API_KEY.
# - claude_code: there's no oauth-personal equivalent. Run
# `claude setup-token` once (ties to your Pro/Max subscription rather
# than a Console API key) and save the result to
