Generalise the front-matter completion into a reusable, provider-based helper
(browse/js/yaml-complete.js) and wire BOTH YAML editors through it. Still fully
deterministic — every candidate and doc string comes from a schema, no AI.
- yaml-complete.js: shared CodeMirror plumbing (indent→key-path, sibling scan,
show-hint, debounced hover tooltip) + two providers:
· flatProvider — a fixed field list (front matter), with an exclude set.
· schemaProvider — a JSON Schema walker that resolves nested key-paths
through properties / additionalProperties / patternProperties and the
recursive $ref:"#" .zddc uses for paths:; keys from object properties,
values from enum / boolean, hover docs from `description`.
- .zddc editor (preview-yaml.js): fetch /.api/zddc-schema once and attach the
schemaProvider on .zddc files — nested-key completion at every level, enum
values (default_tool, dir_tool, views.*.tool), booleans, and hover docs.
Plain .yaml stays lint+highlight only.
- Front-matter editor (preview-markdown.js): refactored to delegate to the
shared helper via flatProvider (excluding the filename-driven identity keys);
the bespoke frontMatterHints is gone — one implementation now.
- Hover-doc tooltip styling.
