feat(domain): naming template engine (Jinja safe subset, MP variables, path layout)

- naming/engine: lexer/parser/AST/render for {{ }} / if-elif-else / whitelisted filters
  (default pad pad2 upper lower trim replace truncate date join); rejects for/set/attribute/
  subscript/call/~/% with line:col errors and 'did you mean' hints
- naming/variables: variable table aligned with MoviePilot names plus ours (cut, airDate,
  issue, slotName, libraryRoot ...); buildNamingVars from parsed release + entity + units
- naming/layout: split by literal '/', segment roles (category/root/season/sub/file),
  value escaping, reserved names, 255-byte segments, validateNamingTemplate
- naming/defaults: MP default movie/tv + our variety template, v1 syntax upgrade,
  entity > root > global override resolution, builtin preview samples
- path/binding: resolveTargetDirectory keeps bound dirs, only unbound segments render;
  renderMediaFileName = last segment of the full template; DEFAULT_TEMPLATES = MP v2
- differential: 34 cases vs MP (21 identical, 13 documented deviations)
