Remove the breaktimer cardHEADmaster

breaktimer is parked and no longer runs, so the card only ever showed
"no breaktimer data". Drop the widget, its sampler and the texeci that
ran it every 5s, the parser and its tests, the icon, and the doc examples
that used it.

--- The breaktimer cache written by bin/breaktimer-sample.sh.
---
--- Returns a table describing the daemon, or nil when the cache is absent or
--- carries no 'generated' key (the sampler never ran). The display strings are
--- derived here rather than in the widget so the phase-to-word and
--- phase-to-colour decisions can be tested without Cairo:
---
---   { running, state, phase, frozen, remain,
---     countdown = '24:31' or '--',
---     phase_label = 'working' | 'micro-pausa' | 'pausa lunga' | 'in pausa'
---                   | 'outside working hours' | 'fermo',
---     next = 'pausa' | 'lavoro' | '--',
---     role = 'ok' | 'heading' | 'highlight' | 'warning' | 'label' }
---
--- `frozen` is the sampler's read of whether the clock is ticking: the phase is
--- 'working' but the remain file has stopped being rewritten. Outside the work
--- window that is normal and reads as such; a hung daemon looks the same, and
--- should.
---
--- The countdown leads to the next phase, but the daemon keeps the cycle count
--- in memory and never writes it, so whether the NEXT break is a micro or a long
--- one is not knowable here. 'pausa' is the honest answer; the phase word carries
--- the rest.
