v0.15.0

Added

• Block AST node and StmtKind::Block; always-braced bodies (function, method, closure, try/catch/finally, braced namespace, property-hook block) now hold a Block, so "this body is a block" is enforced by the type rather than an out-of-band invariant (php-ast).
• ClassBody/EnumBody/SwitchBody wrappers and brace/keyword offset fields (else_kw_start, finally_kw_start, match brace, trait-use adaptations brace). Position data is #[serde(skip)] and Block is #[serde(transparent)], so serialized AST is unchanged (php-ast).
• visit_block, fold_block, owned_block, and av_block to thread Block through both visitors, both folds, and the owned↔arena conversions (php-ast).

Fixed

• Printer preserves a comment that sits immediately before {, else, finally, or the while of a do-while (and other braced/keyword positions) instead of dropping or misplacing it (php-printer).
• Multiline @tag bodies now join continuation lines with a newline instead of a space, so a type expression and its description stay on separate lines (e.g. @var T followed by an indented description) and consumers of body_text/text_content can split them on the boundary (phpdoc-parser).
