Add FieldCardinality to Schema to track required/multiple per field,
populated from the ast_types.yml suffixes (bare = required single,
? = optional single, + = required multiple, * = optional multiple).
dump_ast_with_type_errors now emits:
<-- ERROR: missing required field 'name'
for any node in the output AST whose declared schema requires a field
that is absent from the actual node.

When a {..expr} splice in an output template is empty (e.g. from an
optional capture that did not match), drop the field entirely rather
than emitting an empty named field. This lets a single rule with
optional captures replace what used to be two near-identical rules.
Also re-renders the corpus to drop the now-suppressed empty fields.

Two changes to parse_query_fields:
- Allow `field: (kind)* @cap` (repetition + optional capture) in field
position, mirroring how it works for bare children.
- When the same field name is declared multiple times in a query (e.g.
`condition: (foo) condition: (bar)`), merge them into a single
ordered list of children rather than emitting duplicate field
entries (which at runtime restart the iterator for the field and
cause the second declaration to re-match from the first child).
Introduce NodeRef as a typed wrapper around node arena IDs. Captures in
desugaring rules are now bound as NodeRef instead of raw usize, which
prevents accidental misuse and enables source-text-aware rendering.
Add the YeastDisplay trait as an alternative to Display: its
yeast_to_string method receives the Ast, allowing NodeRef to resolve to
the captured node's source text instead of printing a numeric ID.
Store the original source bytes in the Ast so that NodeContent::Range
values (from synthesized literal nodes) can be resolved back to text.
Update yeast-macros to emit NodeRef-typed capture bindings and use
Into::<usize>::into where raw IDs are needed. The #{expr} template
syntax now uses YeastDisplay instead of Display.
The effect is visible in the corpus tests: operator nodes now correctly
render as e.g. operator "+" instead of operator "3".

One-shot desugaring rules now skip unnamed nodes (punctuation, keywords,
etc.) since rules are intended to target named nodes only.
Also prevent infinite recursion when a capture refers to the root node of
the matched tree (e.g. an @_ capture on the pattern root).
Additionally fix the swift.rs add_phase call to match the updated 3-arg
signature introduced by the one-shot phase kind commit.

Canonicalize `current_dir()` to match canonicalized file paths (avoids
`\\?\` prefix mismatch on Windows), and normalize backslashes to
forward slashes in relative diagnostic paths.

Drop the `url` crate dependency. When a path can't be relativized
against the source root, emit it as a bare absolute path and let the
CLI's SARIF generator handle URI conversion downstream.
