feat(skd): canonical @autoDates pattern + new params operations + use preservation

Fix-pack from skills-improvements-v4 feedback addressing 6 issues found
during real-world ФСД report development.

skd-compile (v1.10 → v1.11):
- @autoDates: emit canonical БСП pattern for ДатаНачала/ДатаОкончания —
  with title, useRestriction=true, value 0001-01-01T00:00:00, expression.
  Removed availableAsField=false so БСП creates two separate Start/End
  fields in the quick settings panel (was rendering as a single picker).
- StandardPeriod value: always emit v8:startDate/v8:endDate to match how
  1C Designer saves the schema (avoids spurious diff on first re-save).
- parameter shorthand: support [Title] syntax mirroring add-field.

skd-edit (v1.9 → v1.10):
- modify-filter / modify-dataParameter: preserve <use> when @off/@on not
  explicitly set (was silently stripping <use>false</use>). Tristate
  parser: None=don't touch, False=@off, True=@on.
- modify-parameter: support [Title] for setting/replacing <title>.
- rename-parameter: new operation "OldName => NewName" — atomically
  renames parameter, updates &Name references in expressions of other
  parameters (full identifier match only), and dcscor:parameter entries
  in dataParameters of all variants. Query text is not touched.
- reorder-parameters: new operation "Name1, Name2, ..." — partial list,
  named params go first in given order, rest preserve original order.
- StandardPeriod value: same v8:startDate/v8:endDate fix as compile.

Tests: 4 new test cases (rename-parameter, reorder-parameters,
modify-parameter-title, modify-dataParameter-preserves-use).
48/48 passing on both PowerShell and Python runtimes.
