Fabric Variable Library

Use for Microsoft Fabric Variable Library — config-as-code for parameterizing notebooks and pipelines across environments. Covers definition parts (variables.json, settings.json, valueSets/<name>.json — no `format` field, omit it), variable types (String, Boolean, Number, Integer, DateTime, ItemReference), notebook consumption via `notebookutils.variableLibrary.getLibrary('Lib').<var>` dot notation (NOT `.get('lib','var')`) or the `get(\"$(/**/Lib/Var)\")` reference-path form, runtime limits (same-workspace only, no SPN, active value set), the ItemReference kernel-shape trap (dict-like; `.value()` AttributeErrors), Git-sync `InvalidContent (ValueMismatch)` (stale override name or empty value), the blank-parameter + lazy-resolution pattern, the `bool('false')` → True trap, pipeline integration via the `libraryVariables` block, the type-name mapping (Boolean→Bool, Integer→Int, Number→Double, DateTime/ItemReference→String), Expression-object wrapping, `valueSetsOrder`, and the runtime-ID rule for ItemReference.
