📝 WalkthroughWalkthroughThe mobile terminal now supports touch links, long-press selection, native clipboard copying, selection-aware composer controls, and animated copy feedback. Caddy proxies local HTTPS terminal traffic to Wrangler with immediate flushing. ChangesMobile terminal interaction flow

- Around line 185-188: Update the copy-message handling in TerminalWebView so
Clipboard.setStringAsync’s rejection is handled explicitly: invoke
onCopiedRef.current only after a successful write, and prevent clipboard
failures from becoming unhandled promise rejections while preserving the
existing copy flow.
In
`@apps/mobile/screens/`(authenticated)/workspace/[id]/WorkspaceScreen/WorkspaceScreen.tsx:
- Around line 187-193: Update the notice state and handleCopied in
WorkspaceScreen so each copy creates a unique notice identity while retaining
the “Copied” text, then use that identity as HeaderNotice’s key in the
headerTitle rendering. Preserve hideNotice behavior and restart the notice timer
on repeated copies.
In `@apps/mobile/scripts/generate-terminal-html.ts`:
- Around line 725-739: Update updateScrollbar so the hidden/bottom condition
does not remove the visible class while thumbDrag is active; only hide the
scrollbar when the content is exhausted or at the bottom and no drag is in
progress. Preserve the existing behavior once thumbDrag is cleared.
In `@Caddyfile`:
- Around line 5-6: Ensure the launch path for Caddy exports or validates both
CADDY_ELECTRIC_PORT and WRANGLER_PORT before startup, so the listener and
reverse_proxy addresses never receive empty values. Preserve the existing Caddy
configuration and make the variables available to the process that starts Caddy.

Make the port contract explicit before starting Caddy.
CADDY_ELECTRIC_PORT and WRANGLER_PORT determine the listener and upstream. Caddy expands {$...} before parsing, and an unset variable can expand to an empty value. This can leave an invalid address or upstream and prevent the local proxy from starting. (caddyserver.com)
The supplied development-command context does not show where either variable is exported. Ensure the process that launches Caddy exports both variables, or validate them before startup.

Summary
The mobile terminal (xterm.js in a WKWebView) previously had no touch affordances beyond scrolling: links weren't tappable, text couldn't be selected or copied, and there was no scroll position indicator. This PR adds all three, plus closes a keyboard hole the work uncovered.
linkHandler. Opens viaLinking.openURLover the bridge.<pre>overlay aligned to the grid, pre-selecting the run under the finger (URLs to their exact extent). Selection is WebKit's own (grabbers, loupe, callout). A centered native SwiftUI Copy Selection button replaces the quick keys row while selecting; copying (button or system callout) joins soft-wrapped rows into one line, writes the clipboard, and shows a "Copied"HeaderNoticein the header. Select mode lives exactly as long as the selection: deselecting auto-exits (debounced past iOS's mid-gesture selection blips), and a long-press that finds nothing never enters.terminal.sendframing (fix(host-service): send follow-up Enter as a separate delayed write so terminals send submits reliably #6284). The page now refuses textarea focus unless RN explicitly requests it over the bridge.HeaderNoticemoved from the pull-request screen toworkspace/[id]/components(now shared by both screens).Test plan

Summary by cubic
Adds tap-to-open links, native long‑press text selection with copy, and a drag scrollbar to the mobile terminal, and blocks the webview from opening the soft keyboard. Previously taps didn’t activate links, text couldn’t be selected, and no scroll position cue was shown.
