Merge dev-v3.2.0 into dev

[jgperrin]

Rollup of the v3.2.0 work that has landed on dev-v3.2.0 since #301 merged.

What it brings

• Teradata server type (#318, RFC 0057) — teradata type, required host, optional port (default 1025) and database.
• Actian server types (#319, RFC 0059) — ingres, vectorwise, versant and poet, plus fastobjects as a synonym of poet and btrieve as a synonym of zen.

Both schema files stay in lockstep; every new server type ships with docs, a positive example, and a negative test.

Merge

Clean merge this time — no conflicts to resolve. dev contributed only the sync-main-into-dev merge (#316), which does not touch the same regions.

Validation

validate-negative.sh and validate-examples.sh both run clean on the merged tree against both schema files (JSON_SCHEMA_VERSION unset and =latest) — four runs, Total failed=0, exit 0 each.
