mARTin-B78 a104f2cfc4 Add modifier-key input scheme (whisper-key style)
New inputmode.py: Ctrl+Win start, Ctrl stop+paste, Alt stop+paste+Enter, Esc
cancel; toggle and push-to-talk variants. Low-level pynput Listener with arming
so stop/send/cancel only fire while recording and only after the start chord is
released — a stray Ctrl tap while idle does nothing (unit-tested).

Daemon split into start/finish/cancel_dictation (+ send_enter -> press Enter),
with start_input/stop_input dispatching between "modifiers" and "hotkeys" modes.
New [input] config section; paste.press_enter for auto-send. Default mode is
"modifiers"; voice-keyword routing still applies to what you say.

"""Deliver text into the focused window via xdotool (X11).
Two strategies:
- "type" : xdotool types the text directly (no clipboard side effects).
- "paste" : put text on the clipboard, then send Ctrl+V.
The target window is captured when recording starts and re-activated before
delivery, so a brief focus change during processing doesn't misfire.
