feat(console): Filesmith console for filesmith commands

[Maxaubert]

Closes #39

What

A Filesmith console: a bottom panel under the files view that runs filesmith commands (and only those) in a forked CLI process, built to the signed-off mockup docs/mockups/console/01-bottom-panel.html and spec docs/superpowers/specs/2026-10-06-console-design.md.

• Open/close: the Console button in the bottom strip of the centre column (on every tab; it replaces the removed totals row, and the open panel sits above it), and Ctrl+`` everywhere (matched on code === 'Backquote'` for Nordic layouts; not under an open dialog). Resizable by a sash (pointer and ArrowUp/Down), height stored.
• Runs: one command at a time, in the console's folder (last folder, else Downloads, else home). Each run is a forked cli.js under the app's own executable with an IPC channel: human text plus NDJSON events for the live progress row. Runs never join the queue.
• Stop / Ctrl+C: staged (IPC interrupt, again, then tree kill after 5 s); a stopped run reports exit 130.
• Limited by design: the first word must be a catalog command or alias (after an optional filesmith prefix and global flags). Anything else (del *.*, claude, paths, operators) is refused with one plain line of text (no button). Main reclassifies the raw line itself before forking; it never takes an argv from the renderer.
• Built-ins: cd (relative, .., quoted, ~, D:, cd -), clear/cls/Ctrl+L, help, history (100 lines, session only, no scrollback across restarts).
• Completion: catalog-driven Tab completion for commands, flags, values and files; Up/Down history.
• Output: result rows, summary with Show in File Explorer, right-click a result row for Show in File Explorer / Open in default app.
• View-size keys (Ctrl+=, Ctrl+-, Ctrl+0) no longer change the files view while typing in any text field; Ctrl+wheel over the console neither steps the view size nor zooms.
• Progress reads like the queue, no space before the bracket: 63%(4s) in the console and in the CLI's human output.
• Version 0.8.0 (minor, feature).

Owner feedback on 0.8.0 (commit 8318179)

• Folder button toggles: a second click on the console head's folder button now closes its menu. Cause: the shared context menu closed on any window mousedown, then the button's click opened it again. Menus opened from a button now carry their trigger; a press on the trigger is left to its click, which toggles (menuToggle.ts). The View menu and the option selects already excluded their trigger and toggled; e2e now pins both the folder and View buttons (open, close, open).
• Bottom strip: the totals row is removed (TotalsRow, queueTotals and their CSS and tests deleted). A 30px strip flush with the window bottom holds only the Console button (pressed while open) on every tab, Generate, PDF Tools, Completed and Settings included. The files toolbar is Add files, the count and View.
• Progress format: 62%(4s) everywhere (console panel and CLI human reporter; tests and spec updated).

Hands-on, scripted against the built app (hidden window, fresh profile):

• `Ctrl+`` opens with the prompt focused and closes again; the strip's Console button opens it. Default folder: Downloads.
• doctor: exit 0, tool table printed.
• convert sample.png --to webp in a temp folder: ok sample.png -> sample.webp, exit 0, Show in File Explorer shown, file written, queue row count unchanged.
• del *.* and claude: not run, plain refusal line; a direct consoleRun of calc through the bridge is refused by main.
• Tab: conv to convert ; files listed for sam; --to we lists webp/webm and Enter inserts webp. Up recalls claude, then del *.*.
• A 31-file avif --quality best run: live row [12/31] big11.png 63%, Stop gives exit 130, Stop button gone, no partial outputs left.
• cd .. moves the folder up and prints the note.
• Ctrl+= / Ctrl+Shift+= in the prompt: view size stays details, zoom stays 1.

Implementation shots next to mockup 01 match in layout, greys, Stop in red and the Console button; differences are only the HiDPI scale and the long temp path in the prompt.

Known gaps

• The mockup's open-idle shot shows an intro paragraph ("Runs filesmith commands in this folder ...") at the top of the scrollback. The spec does not list it (an empty scrollback shows the placeholder convert *.heic --to webp), so it is not built. Say if you want it.
• The Show in File Explorer click was not exercised by the script (it opens a desktop window); the e2e checks the button.
• Unsigned installer, as for every release until SignPath enrollment.

🤖 Generated with Claude Code

• Tooltips: removed those that repeat a visible label (sidebar when expanded, Console button, Add files, Run, View, Stop, console note); kept on icon-only buttons, collapsed sidebar items and truncated paths.

• Console simplified (owner feedback): open, the panel replaces the bottom strip flush with the window bottom; its head is a slim 28px row with only the close X (plus the red Stop while running). Folder menu, note and Clear left the head; cd / clear / Ctrl+L still work.

• Extra UI removed (owner feedback): no Open in terminal anywhere (launcher, IPC, preload, icon, tests removed), no keycap hints at the prompt or in the completion list (Tab, Up/Down, Enter, Esc still work). Refusal: `del` is not a filesmith command. Only filesmith commands run here. Use a terminal for anything else.
