fix(lint): resolve all three CI lint job failures

1. lint (ruff_strict_gate) — UP006/UP045/F401 violations introduced on
   changed lines. Fixed Dict/List/Optional/Tuple → built-in equivalents
   across every file in the PR diff; cleaned up now-unused typing imports.

2. any-discipline — RecursionError in check_any_discipline.contains_any()
   on deeply-nested mypy types. Upstream fixed this by converting to an
   iterative stack-based algorithm (merged). Also added deepkeep.py to
   any-discipline-budget.json via 'make lint-any-budget-update' so the
   new file's Any count is baselined instead of failing against the
   zero-baseline default.

3. basedpyright reportMissingParameterType — **kwargs in DeepKeepGuardrail
   __init__ lacked a type annotation. Added **kwargs: Any.
