v0.3.2

Upgrading

• Rebuild with make all. Gold migrations 0107–0108 apply on the first
  read-write open. No reload is needed.

Demo

• make demo builds an invented household into its own directory,
  ~/wealthdb-demo by default: three years of one family's accounts,
  holdings, transactions, returns, spending, income and cash flow,
  written as synthetic silver sources and loaded through the ordinary
  init and load -a, so every report and dashboard shows real
  behaviour. make demo-web serves its dashboards on
  http://127.0.0.1:3100/ in a container of their own, and
  make demo-web-stop stops them.
• make demo-roll adds the days since the last build and loads only
  those. History never changes between runs.
• WEALTHDB_DEMO_ROOT, AS_OF, SEED and FINDINGS=1 select the
  directory, the end date, the random seed and a build with a few planted
  imperfections for the diagnostic surfaces: uncategorised purchases, an
  unpaired transfer, a coverage gap and a stale source.
• Nothing in the demo comes from real data. Every person, institution,
  merchant, company, fund and ticker is invented. demo/disjoint.py
  lists every identifying value a demo gold shares with another gold,
  and demo/check_dashboards.py runs every dashboard card against a
  Metabase and reports failures.
• A new silver kind, synthetic, reads a silver shaped like the
  canonical model itself: one table per record type, passed through
  with the usual guards. It is generator-fed, its runs are append-only,
  and a load takes only the runs past its watermark. A row's provider
  category is a taxonomy value and is filed as such. See
  wealthdb/docs/adapters/synthetic.md.

Reports

• Cash flow coverage: an account whose transactions reconcile exactly
  with its balances reads measured with a gap of zero. It read
  obscured before.
• Data Freshness dashboard: the declared accounts' source no longer
  shows as the stalest source. It has no feed and no snapshot.

Build and docs

• Go dependencies updated.
• The README describes the demo and how to try it.
