fix(ci): update ARCHITECTURE.md counts and add TEXT_MODE fallback to sketch workflow (#2377)

* fix(tests): clear CLAUDECODE env var in read-guard test runner

The hook skips its advisory on two env vars: CLAUDE_SESSION_ID and
CLAUDECODE. runHook() cleared CLAUDE_SESSION_ID but inherited CLAUDECODE
from process.env, so tests run inside a Claude Code session silently
no-oped and produced no stdout, causing JSON.parse to throw.

* fix(ci): update ARCHITECTURE.md counts and add TEXT_MODE fallback to sketch workflow

Four new spike/sketch files were added in 1.37.0 but two housekeeping
items were missed: ARCHITECTURE.md component counts (75→79 commands,
72→76 workflows) and the required TEXT_MODE fallback in sketch.md for
non-Claude runtimes (#2012).

* fix(ci): update directory-tree slash command count in ARCHITECTURE.md

Missed the second count in the directory tree (# 75 slash commands → 79).
The prose "Total commands" was updated but the tree annotation was not,
causing command-count-sync.test.cjs to fail.

 Parse `$ARGUMENTS` for:

 - Remaining text → the design idea to sketch

+**Text mode (`workflow.text_mode: true` in config or `--text` flag):** Set `TEXT_MODE=true` if `--text` is present in `$ARGUMENTS` OR `text_mode` from init JSON is `true`. When TEXT_MODE is active, replace every `AskUserQuestion` call with a plain-text numbered list and ask the user to type their choice number. This is required for non-Claude runtimes (OpenAI Codex, Gemini CLI, etc.) where `AskUserQuestion` is not available.
