v0.6.0

Removed

• --layout sane, and the make sane target. Renamed to tree in 0.5.0, where
  it was deprecated with this version named in the warning, the code, the tests
  and the changelog. --layout sane is now an argparse error listing the valid
  choices, and Style(layout="sane") raises. One release of overlap was the
  whole point of promising a version rather than leaving it open-ended, which is
  still the right call for the UDM_* environment names.

Added

• TODO.md, the planned work in one contributor-facing place, since the
  alternatives were a context file written for AI agents and a Jira instance
  needing an account. Two tests keep it honest: it may not plan work for a
  released version, and its commitment section must name the same version the
  deprecation warning tells users.
• --transparent draws no canvas, so a map can be dropped onto a page that
  already has a background. Covers SVG, PDF, PNG and draw.io. The theme still
  applies and still matters: with the default icon set, labels have no card
  behind them, so on a transparent canvas they land straight on the destination
  page and a light map is near-invisible on a dark one.
• Every demo screenshot is committed in both themes rather than only dark, so
  the documentation shows what the default actually produces instead of
  describing it.

Fixed

• RELEASING.md describes the process as it now is. Four things in it were
  wrong. It said to rename ## Unreleased away at release, which would delete
  the section CONTRIBUTING.md tells contributors to use. It never mentioned
  make docs, which is mandatory now that the man page carries the version. It
  said CI could not be checked from here, which stopped being true once gh was
  installed; the instruction now runs gh run watch and says to read the
  per-job output, because Dependency advisories is continue-on-error and
  reports success having failed inside. And it counted how many times things had
  happened, where two of the counts were wrong and none told a reader anything
  the sentence did not.
• CLAUDE.md said the sane layout alias goes in 0.5.0. It goes in 0.6.0,
  which the code, the tests and the changelog all said; that one heading was
  missed when the promise moved.

Changed

• --site's help text no longer reads as though multi-site support files are
  refused outright. They are refused only when you do not say which site you
  want, which the sentence did say, twenty words earlier, in a table cell. It
  now states the requirement rather than the refusal. The README prose leads
  with the same.
• Dependabot auto-merge holds anything whose update type it cannot identify,
  rather than merging it. The condition asked "is this not a major bump", which
  treats an empty or unrecognised value as safe, so anything leaving
  update-type unpopulated made the step an unconditional merge. Not
  hypothetical: fetch-metadata resolved update-type to null for Python pull
  requests until v3.1.0, and Python dependencies are what this repository
  tracks. It now asks "is this a minor or patch bump", so an unknown value
  merges nothing.
• A test asserts the man page header carries a real date. The date comes from
  the changelog entry for the current version, so bumping __version__ before
  dating that section produced an empty one, and the regenerate-and-compare
  check could not see it because both sides were generated the same wrong way.
