Placeable class final

A { ... } placeable. Wraps an Expression and appears in two positions in the AST:

• As an element inside a Pattern (the common case — that's how placeables interleave with pattern text).
• As an InlineExpression inside ANOTHER placeable's expression slot — i.e. nested placeables { {"x"} }.

The dual role is required by the Fluent Syntax 1.0 spec. It only works because every AST file is part of one Dart library, so the sealed PatternElement and sealed InlineExpression boundaries can both legally cover this class.
