Commit Message

Cover error paths for union vectors and mismatched schemas

## Why

Four reachable error branches had no tests: the writer's handling of
union vectors (which the schema parser accepts but the writer cannot
encode), and get/4's defense against a schema whose entities disagree
with the buffer (an unrecognized field type, or a missing table
definition).

## What

- Writing a vector of unions throws wrong_type per element; writing an
  empty one throws unknown_scalar when sizing the elements.
- get/4 raises BadFlatbufferError when the schema names a field type
  reading does not recognize, and when the table definition for the
  path is absent from the schema.

Coverage rises from 98.5% to 99.3%; access.ex and reading.ex reach
100%. The three remaining uncovered lines are defensive clauses
unreachable through any parseable schema.
