Maintenance note

I've picked up maintenance of this project. My priority for the near term is working through the backlog of confirmed bugs before picking up new feature requests — thanks for your patience, and especially to everyone whose detailed bug reports, repro configs, and PRs made several of these fixes possible.

What's new

• mega<0-9> and milli<0-9> number formats, plus kilo<0-9> for an explicit decimal precision override (kilo alone is unchanged, still backward compatible):

  - entity: sensor.power_usage
    type: custom:multiple-entity-row
    format: kilo3   # e.g. 1500.256 W -> 1.500 kW (set unit: kW yourself if you want the label to match)

Fixed

• name override not applying on the main row on HA 2026.2+ until an unrelated entity update forced a re-render (#370, #371) — thanks @d3relict for the diagnosis
• format: duration/duration-m/duration-h showing the literal string "null" for a zero-second value (#240)
• Numeric formats (brightness, precision, kilo, invert, position, celsius/fahrenheit conversion) showing the literal string "undefined" for a missing attribute (#225)
• invert/position formats losing decimal precision compared to the unformatted value, and kilo/mega/milli precision handling generally (#304) — thanks @Jueff for the original kilo/mega idea
• A long-standing cluster of decimal/currency/precision formatting bugs (#333, #308, #286, #220, #375, #363, #357, #320), by switching to Home Assistant's own official formatting functions when available (HA 2023.9+) — thanks @mill1000 for the approach
• Console spammed with errors for monetary sensors using a non-currency unit like "c/kWh" (#324)
• Missing-attribute display showing "undefined" on older HA versions without the official formatting functions

Internal (no action needed, but relevant if you build from source)

• Added a real test suite (100+ tests), CI, and automated release tooling — the built JS file is no longer manually committed per release, it's built and attached automatically by CI
• Bumped lit (2→3) and custom-card-helpers (1.8→2.0) — bundled into the built file, doesn't affect how you install or use the card
• Fixed 57 known vulnerabilities (4 critical) in the dev/build toolchain
