chunkedTerminalWrite used requestAnimationFrame to write buffer chunks across
frames but had no cancellation. When switching tabs, old session's remaining
chunks continued writing stale data into the new session's terminal, causing
visual artifacts and garbled content.
- Add _chunkedWriteGen generation counter to abort in-flight chunked writes
- Bump gen early in selectSession() and SSE reconnect to immediately cancel
- Guard finish() so aborted writes don't flush SSE queue for wrong session
- Add fitAddon.fit() before buffer writes to sync terminal dimensions
- Add fitAddon.fit() in sendResize() to ensure local/server dim parity

xterm.js DOM renderer doesn't populate .xterm-viewport's scroll area (the div
is empty, scrollHeight === clientHeight), so native CSS scrolling via
touch-action:pan-y and overflow-y:scroll had nothing to scroll. Desktop worked
only because the wheel handler called terminal.scrollLines() directly.
- Replace split mobile/desktop touch handlers with unified JS-driven handler
that converts touch deltas to terminal.scrollLines() calls (with pixel
accumulation for slow swipes and momentum scrolling)
- Change touch-action from pan-y to none on terminal elements so browser
doesn't fight the JS handler
- Remove now-unnecessary xterm-viewport position/overflow/z-index overrides
and iOS -webkit-overflow-scrolling rules
- Fix _shrinkPaddingToFit() arithmetic (was adding gap instead of subtracting)
- Minor: add route-helpers.ts to CLAUDE.md, fix sse-events.ts comment count

Split the monolithic app.js (~12.5K lines) into 6 focused mixin modules
that extend CodemanApp.prototype via Object.assign:
- terminal-ui.js — terminal setup, rendering pipeline, controls
- respawn-ui.js — respawn banner, countdown, presets, run summary
- ralph-panel.js — Ralph state panel, fix_plan, plan versioning
- settings-ui.js — app settings, visibility, web push, tunnel/QR, help
- panels-ui.js — subagent panel, teams, insights, file browser, log viewer
- session-ui.js — quick start, session options, case settings
Fix deferred script init ordering: wrap CodemanApp instantiation in
DOMContentLoaded so all defer'd mixin modules execute their
Object.assign before the constructor runs. Without this, init() calls
methods like applyHeaderVisibilitySettings() that don't exist yet.
Guard missing cleanupWizardDragging() call in subagent-windows.js.
Update build.mjs to minify/hash all new modules. Update CLAUDE.md
with new frontend architecture and load order.
