term/osk: scroll region so the OSK never hides the input line
The terminal now has a variable usable height (wTermRows). term_scroll and
cursor_down operate within [0 .. wTermRows-1], and term_set_rows(n) shrinks
or grows that region, scrolling the cursor up into view when it would fall
outside. osk_toggle shrinks the terminal to the rows above the keyboard on
show (18 - OSK_ROWS = 15) and restores full height on hide, so the active
line is always visible just above the docked keyboard, and hiding the OSK
reclaims all 18 rows.
Also add c/count.c ("count [n]", default 25): prints n numbered lines to
observe/debug scrolling and the scroll-region behavior. Registered as
program id 21 / bank 23. Fixed the arg to read argv[0] (getargs returns the
string after the command name).
Verified: filling the screen then opening the OSK scrolls the latest line
to row 14 (visible) with the keyboard at 15-17; closing it restores rows
15-17; count N prints exactly N lines.
