• Update dependencies.
• Remove some dependencies.
• Requires node version >= 22.9.0, hence the major version change.
• Update search tags in doc.
• Fix bug in strategy-functions: guard the handleStrategyInput result instead of
  destructuring it, so a payload-less or command-only message before any
  price data no longer crashes every strategy node.
• Fix bug in schedule-merger: compare the period a schedule covers instead of its last
  collapsed entry, so saving a second strategy's schedule stops deleting the
  first one.
• Fix bug in schedule-merger: look every source up at each switch point instead of
  transposing on timestamp keys, so a source covering a longer run can no
  longer drop out of the OR/AND merge.
• Fix bug in strategy-lowest-price: seed the running minimum with Infinity, not the sum
  of all values, so negative prices no longer make it pick the most
  expensive slot.
• Fix bug in utils: addEndToLast no longer reads index -1 for a single price record.
• Fix bug in handle-input: infer the last record's missing end instead of dereferencing
  the next record, and plan the final period rather than dropping it.
• Fix bug in general-add-tariff: call substring on p.start, not on the period object,
  so tariff periods with HH:MM starts work.
• Fix bug in heat-capacitor: findTemp accepts the ISO string it is given from
  msg.payload.time, which previously compared as NaN and always returned the
  last schedule entry.
• Fix bug in light-saver: rebuild the event bus subscriptions when the entities in the
  config change, and unsubscribe from what was actually subscribed, so
  dynamic config takes effect and no listeners leak across redeploys.
• Fix bug in light-saver: skip only the timeout check when a trigger is on, not the
  whole function, so the documented Immediate level still applies.
• Fix bug in handle-output: wait in chunks above the 32 bit setTimeout limit, instead
  of switching immediately for anything more than ~24.8 days ahead.
• Fix bug in schedule-merger: optional chaining on the msg.payload reads, and return an
  empty schedule from makeScheduleFromMinutes when there is nothing to merge.
• Fix bug in strategy-fixed-schedule: fall back to outputIfNoSchedule when periods is
  empty, instead of dereferencing undefined for every hour.
• Fix bug in handle-input: malformed priceData was warned about but accepted anyway,
  because the check returned from inside a forEach callback. Such a message is now
  rejected. Prices given as strings are still accepted, and are converted to
  numbers before planning. Thanks to @anupamme for reporting it.
