feat(response-viewer): ASCII diagram wrap toggle, mobile code blocks, chrome-stripping fallback (#75)
* fix: restore clear message separation + proper table layout in response viewer * fix: capture Claude CLI's real session ID + robust ANSI/CLI-chrome stripping in response viewer fallback Session constructor seeded _claudeSessionId with Codeman's session.id as a placeholder, and the message-driven update was gated on !_claudeSessionId — meaning Claude CLI's actual session UUID was never adopted. This broke /api/sessions/:id/last-response JSONL lookups, silently falling through to the terminal-buffer path whose ANSI regex missed \x1b[>c / \x1b[>q queries. - session.ts: update _claudeSessionId whenever a message's session_id differs from current (covers placeholder and stale-resume cases) - app.js: extract _cleanTerminalBuffer with proper CSI regex (param bytes 0x30-0x3F now covers > ? < =) plus a chrome filter for status bar, progress bar, spinner, shell prompt, and hint lines * fix: wrap regular code blocks on mobile, keep ASCII diagrams rigid with scroll hint * feat: add per-block wrap toggle on ASCII-diagram code blocks * fix: wrap by default, pin toggle button outside scroll container * fix: narrow diagram detection to box-drawing + block elements only * feat: show last-response viewer eye icon on desktop too The response viewer button was mobile-only via a display:none default with a mobile.css override. Flip the default to inline-flex and drop the override so the eye icon appears in the header on every form factor — desktop users get the same quick "Last Response" pane as mobile. * fix(response-viewer): restore HTML sanitizer + fix undefined `src` in _renderMarkdown - `_renderMarkdown` referenced an undefined `src` (should be `text`), causing a ReferenceError on every markdown render. The try/catch swallowed it, so the new table-wrap and ASCII-diagram features never actually ran — output silently fell through to plain-text. app.js is excluded from ESLint, so this wasn't caught at lint time. - `_sanitizeHtml` was removed when refactoring the response viewer, leaving `marked.parse()` output going straight into `innerHTML` without sanitization (XSS regression vs. master). Restored the helper and re-applied it before any post-processing.
