Log Message:
SyncTERM: move transfer-window UI to Wren

Replace the C-side draw_transfer_window/transfer_complete plumbing
and the per-protocol cprintf progress callbacks with a Wren
TransferApp driven by a worker thread + bounded mailbox. C side
runs each protocol on its own thread and pushes pre-formatted
status lines through xfer_tick_lock/get/unlock; the main thread
stays in TransferApp's modal loop, which composes ProgressBar and
LogView widgets.

Worker-to-main marshalling covers the two thread-unsafe UI paths: duplicate-file resolution and the YMODEM->XMODEM filename prompt
fallback. All six protocol entry points (zmodem recv/send/batch,
xmodem/ymodem recv/send/batch, cet recv) now flip binary mode and
hand off to wren_run_transfer; lputs auto-routes via the mailbox
when xfer_session_active().

Drops ~1100 lines of C Ä the legacy log_ti/progress_ti/transw_ti
windows, ask_overwrite, the per-protocol progress functions, and
the cputs-into-window logging path.

SyncTERM: move begin_upload / begin_download to Wren

Replace the C-side begin_upload() and begin_download() uifc dialogs
with Wren UploadApp / DownloadApp classes Ä protocol picker uses
ListView, file selection goes through Host.pickFile / pickFiles
(uifc filepick wrapper), XMODEM filename via Prompt.

Three new Transfer foreigns dispatch into the existing protocol
entry points: Transfer.upload(kind, path, lastCh),
Transfer.uploadBatch, Transfer.download. Kinds are stringly-typed
("zmodem", "ymodem-g", "xmodem-1k", "cet", ...) so the C side can
fan out to the right xmodem_*/zmodem_*/cet_telesoftware_download
call without exposing mode flag bits to Wren.

The foreigns can't run wren_run_transfer directly Ä wrenCall is
forbidden from inside a foreign method (wren.md 7). They record
the user's choice in a single-slot xfer_pending struct and return
immediately; xfer_drain_pending(), called from doterm() at C
top-level, runs the actual dispatch. Auto-Z drains right after wren_run_upload_app() returns; Alt-D / Alt-U are picked up at the
next outer-loop iteration.

Hook.onKey for Alt-D / Alt-U lives in keys_default.wren (matches
the Alt-B / Alt-C / Alt-X migration pattern). Conn.upload() and Conn.download() Wren foreigns are gone Ä online_menu now calls
UploadApp.run / DownloadApp.run directly.

Deletes ~210 lines of C: begin_upload, begin_download, the Alt-D /
Alt-U switch cases in doterm(), fn_Conn_upload / fn_Conn_download.

SyncTERM: move font_control to Wren

Replace the C-side font_control() uifc dialog with a Wren FontApp
class. The picker uses ListView over Font.name(0..count-1), with
Insert keying into Host.pickFile + Font.load(file). Hook.onKey
for Alt-F lives in keys_default.wren; online_menu's "Font Setup"
entry now calls FontApp.run() instead of Host.fontControl().

Two new foreigns:
- CTerm.altFont / CTerm.altFont=(slot) Ä getter/setter for
cterm->altfont[0]. Setter calls ciolib_setfont(slot, false, 1)
and updates the cache.
- Font.load(file) Ä takes a File foreign (not a path string) and
extracts the path internally via the new wren_file_path() helper
in wren_bind_fs. Keeping bare paths out of Wren preserves the
consent-token model: only paths the user explicitly approved
through a picker can be opened.

Two pre-existing bugs surfaced by this work, fixed in passing:
- ListView.preferredHeight returned the unbounded item count, so a
pane with fitContent() over the 100+ populated font slots
overflowed the screen. Cap it at screen height minus a chrome
budget (ListView already scrolls).
- ListView.handleKey_ didn't guard `cp` before `cp >= 0x20`, so any
extended key with null codepoint (Insert, function keys, arrows)
that fell through the explicit handlers crashed with
"Null does not implement '>=(_)'".

Deletes ~75 lines: font_control() in term.c, the Alt-F switch case
in doterm(), fn_Host_fontControl() shim, Host.fontControl()
declaration.

wren: route file selection through the picker VM

Run file selection in a third persistent Wren VM so menu and
connected scripts never execute the picker implementation directly.

Expose only directory listings, path resolution, metadata, and a
one-shot completion object to picker scripts. Preserve the existing
single, directory, save, and cross-directory multi-select behavior.

Carry create-versus-overwrite consent out of the picker explicitly.
Save and restore screen, mouse, and cursor state in C, with input
barriers on both ownership transitions.

Keep picker errors inside a recovery screen where Escape cancels and
Ctrl+` opens the picker-local REPL.

Log Message:
wren: center the file picker pane

Inset the picker frame by two columns on each side so its body is
centered while the two-column right shadow occupies the remaining edge.

Start the frame on the second row and leave the final row for its bottom shadow. This preserves the existing top line without unnecessarily
shortening the file lists.

wren: restore font picker options

Match the custom-font editor with its C predecessor by enabling direct
Path entry and leaving its size-specific mask editable.

Restore the connected Alt+F loader to its original no-option behavior.
Both Wren migrations had substituted literal bit 1, which locks the mask,
for the distinct flags used by the previous callers.

Log Message:
Allow menu console from submenus

Register Ctrl+` directly in the App global keymap instead of through
the main-menu binding helper. That helper intentionally ignores commands
while a modal is open, causing the console shortcut to be consumed without opening the REPL in settings, help, and editor panes.

Keep the top-level guard for ordinary menu commands while allowing the
current modal to remain mounted behind the console.
