The X11 source only re-read the active window on _NET_ACTIVE_WINDOW
changes, so switching a browser tab — which changes the window title
but not the active window — was invisible. All the time on the new tab
was credited to the stale title (e.g. reading a Consume article showed
up as time on the Keel tab).
Mirror the Windows sensor: poll the active window every 750ms and emit
only when the window or its title changes. A shared, display-free
pollLoop carries the change-dedup and is unit-tested for the exact
regression (a title-only change must emit).

Remove the legacy/ Rust tree (Cargo manifests, .rs sources, desktop
entry), drop Rust-specific .gitignore blocks and README note, and strip
now-dangling "ported from Rust" comments from the Go sources.

Bucket keys are {Class, ScrubTitle(Title)}, so each animated progress frame a
terminal app cycles into its title (Claude Code's braille and dingbat-star
glyphs) became a distinct bucket — fragmenting one task into dozens of rows and
inflating the switch count, since applyEvent counts a switch per key change.
ScrubTitle now drops any non-ASCII symbol or control rune and collapses leftover
whitespace. This is category-based rather than range-based, so future spinner
sets are covered too, while letters and digits of every script survive and ASCII
symbols (e.g. "C++") are left intact.
