v3.0.0

A wide one - the first release in months, and most of what Home Assistant did
to this card since the last one is fixed here. It is a major bump because two
of the changes are visible: the dropdown menu is the card's own now, and the
element registry is global.

Added

• hide_icon - a boolean or a template. Hide the entity icon on the left,
  or hide it only while a condition holds, the way every other hide in this
  card works. #248

Fixed

• The card is no longer a blank box when its entity is missing. An entity
  that is not in hass.states at all - renamed, deleted, an integration still
  starting - used to render an empty card and throw once per component. Now it
  draws the unavailable card. #46
• tap_action written as a string works again. tap_action: more-info and
  the rest - the shorthand that a hand-written card uses - was a dead click on
  the card itself. The indicator never had this bug; the card's own click did.
  #234
• The entity icon lines up with what is beside it. The mode and the
  temperatures sat 4.5px low against the icon, and the name 10px high when the
  secondary info line was hidden. Both are now centred on the same row.
  #99,
  #100
• The icon button fits its host on Home Assistant 2026.x. HA rebuilt
  ha-icon-button on ha-button and moved the size from
  --mdc-icon-button-size to --ha-icon-button-size; the card now sets both,
  so what it draws is 30px, not 30px inside 48px. The same bug also hid the
  dropdown icon. #188,
  #256
• The fan mode dropdown button is the size it should be. It was 30px inside
  a 20x19 host. #256

Changed

• The dropdown menu is the card's own, not @material/mwc-'s. The card no
  longer ships the Material Web Components menu that Home Assistant stopped
  loading - which is what stopped the fan mode and hvac mode dropdowns working
  on HA 2026.5. The menu it renders now is this card's mc-menu. Behaviour
  with a visible dropdown is the same; the internals are not.
  #175
• The element registry is global. Every mc-* component registers itself
  with the document, the way Home Assistant expects a custom card to. Two
  things follow: a component that is not imported is now obvious, and the
  polyfill this card used to depend on is gone. This is the larger part of why
  cast rendering - and the blank card elsewhere - should be healthy.
  #72,
  #80

Removed

• collapse. Declared and read since the first commit, never styled by
  anything, documented nowhere. An option that did nothing for six years is
  gone rather than described.

No change to the card itself

The rest of the 56 commits are the toolchain, the documentation, and the test
bench - none of which changes what the card draws or does. The test layer is
where the effort went: four layers now, one of which is a whole Home Assistant.
