v0.2.0

Binaries for Linux, macOS, Windows and FreeBSD are attached below. The Docker image is
ghcr.io/mariuz/firebirdrest:0.2.0. See CHANGELOG.md for details.

SQL schemas for Firebird 6, chosen per request with Accept-Profile and Content-Profile.
Schema support is experimental: it is tested against the Firebird 6 snapshot and may change
if Firebird 6 changes before its release. Existing setups keep working as before: Firebird 3-5
are unaffected, and Firebird 6 without db-schemas serves PUBLIC as it did.

Added

• SQL schemas (Firebird 6, experimental): db-schemas lists the schemas to expose, the first
  being the default (public when unset). Requests pick one with Accept-Profile (reads) or Content-Profile
  (writes), as in PostgREST; responses carry Content-Profile, and unexposed schemas get 406
  (FBRST106). Each schema has its own cache and OpenAPI description, statements use
  schema-qualified names, and embedding follows foreign keys within the schema.
  examples/bookstore-fb6.sql adds an inventory schema. db-pre-request accepts schema.proc.

Fixed

• On Firebird 6 the schema cache matches system-table rows by schema as well as by name (domains,
  constraints, indexes, routine parameters), instead of relying on names being unique.
