DeckAway v1.55.0

Claude Code's permission prompts reach Telegram, and an architecture review.

• Claude Code's "Do you want to proceed?" is a question again. Since Claude Code 2.1 the permission dialog ends in "Esc to cancel · Tab to amend" and names no Enter key, so the panel did not see it: no Telegram message, no notification, no answer buttons. It now does, and the question carries the command it asks about (with its description), not only "Do you want to proceed?". A connected computer needs this version too for its own prompts.
• Unexpected server errors are logged. A 500 answer left nothing in the journal; now the method, the path and where the error happened are written there, never the error's text, which can carry a token.
• Settings and secrets are written by one helper: always mode 0600, through a symlink never, flushed to disk before the rename. Five slightly different copies had grown; the sessions file used a fixed temporary name, and a leftover one from an earlier version is removed.
• No child process inherits the panel's standard input, so gh or git can never wait for an answer that does not come; a test checks every call.
• CI also runs ruff, ShellCheck and the browser tests (Chromium and WebKit at an iPhone size). The page build fails when a script is missing from the bundle list or a top-level name is declared in two files.
• New documents: docs/ARCHITECTURE.md (components, the path of a question, trust boundaries, design choices, the three names in use), SECURITY.md, CONTRIBUTING.md; outdated passages of DETAILS.md and TESTING.md updated.
