hooks: replace the examples with ones that do what the binary cannot

The previous examples largely duplicated features of the patched build.
on_done sent a desktop notification and played a sound, both of which
the notify patch already does, so a user who copied it got two of each.
on_quit recorded abandoned sessions, but the logging patch calls
write_log() unconditionally at the end of every run: abandoned sessions
were already in the log behind timer -r.

The new set does two things nothing else can:

  - Intent versus outcome. The log stores elapsed seconds only, so a
    finished 25m and an abandoned 30m that ran 25m are indistinguishable
    in it. The duration actually requested is visible to on_start and
    nowhere else, so the examples write START/DONE/QUIT records to
    $XDG_STATE_HOME/ttym/sessions.tsv.

  - Focus mode. During a countdown, pause dunst notifications and any
    playerctl/mpc playback; restore on done or quit. Countdown only, so
    a stopwatch cannot silence notifications indefinitely.

A timewarrior bridge is included but commented out.

Two behaviours documented in the file comments, both read off the code
rather than assumed: notify_and_sound() runs before the on_done hook, so
with dunst paused the completion popup is queued and appears when the
hook unpauses -- delayed, not lost; and nothing restores dunst if the
process is killed with -9.

Every external command is guarded with command -v, so the examples
degrade to the session record alone on a machine without those tools.
Each hook works standalone -- the man page and README now say so
explicitly, since installing only on_quit is a normal setup. All three
pass sh -n and shellcheck, and were tested across all three paths:
completed countdown, abandoned countdown, stopped stopwatch, with
dunstctl is-paused confirmed false afterwards.
