Adds three new AST nodes to the mix: - `TemplateString` represents a t-string in Python 3.14 - `TemplateStringPart` represents one of the string constituents of a t-string. (The interpolated expressions are represented as `Expr` nodes, just like f-strings.) - `JoinedTemplateString` represents an implicit concatenation of template strings. Importantly, we _completely avoid_ the complicated construction we currently do for format strings (as well as the confusing nomenclature). No extra injection of empty strings (so that a template string is a strict alternation of strings and expressions). A `JoinedTemplateString` simply has a list of template string children, and a `TemplateString` has a list of "values" which may be either `Expr` or `TemplateStringPart` nodes. If we ever find that we actually want the more complicated interface for these strings, then I would much rather we reconstruct this inside of QL rather than in the parser.
