v0.11.0

Added

• Compact relation DSL: _rel fields now accept a compact string format in addition to the existing shorthand and verbose object forms
  • "m2o:target" — type + target in one string
  • "m2o:target[1..1->0..n]" — with cardinality notation (carDirect->carInverse)
  • "m2o:target@foreignKey[1..1->0..n]" — explicit FK when the field name differs from the FK column
  • "m2m:target@through(foreignKey,otherKey)[0..n->0..n]" — many2many compact form
  • +nested suffix on any DSL string — equivalent to _nested: true
  • Type aliases: m2o / many2one, o2o / one2one, m2m / many2many
• Cardinality fields on RelationDef: carDirect and carInverse are now stored on every resolved relation and used by /_about E/R diagram to render accurate crow's-foot notation instead of inferring cardinality from relation type
• parseRelations() DSL parser (src/storage/parseRelations.ts): new parseDslString() internal function handles all three DSL levels; all forms expand to the same canonical RelationDef at parse time
• parseRoutes.ts (src/storage/parseRoutes.ts): extracted _routes parsing logic from yrestStorage.ts into its own module
• E/R diagram canvas split (src/router/templates/about.diagram.canvas.ts): the inline JavaScript canvas renderer is now in a dedicated file using the /*js*/ comment tag for editor syntax highlighting; about.diagram.ts retains only TypeScript types and generateERData()

Changed

• _ prefix convention enforced on all yrest reserved keys: verbose relation objects now use _type, _target, _foreignKey, _otherKey, _through, _nested, _car-direct, _car-inverse (all prefixed with _). The previous unprefixed form (type, target, nested, etc.) is no longer supported
• yrestStorage.ts now serialises _foreignKey, _car-direct and _car-inverse back to YAML on snapshot/persist
• init --sample ecommerce and init --sample relational templates updated to use the _ prefix convention throughout

Breaking

• Verbose _rel object keys without _ prefix (type, target, nested, through, foreignKey, otherKey) are no longer parsed. Migrate existing db.yml files by adding _ to each key: type → _type, target → _target, nested → _nested, etc.
