Add TDD-style Behave BDD tests for the built-in fs-directory resource type
bootstrap (bug #523). Three Gherkin scenarios: one failing TDD test
reproducing the bug (no bootstrap called during init, tagged @wip), and
two regression tests verifying bootstrap_builtin_types() seeds correct
data and resource add fs-directory succeeds after bootstrap. Includes
Robot Framework regression tests.
Review feedback addressed:
- Removed all 21 unnecessary # type: ignore comments (hurui200320 M1)
- Fixed is not True to is False for clarity (Aditya F2)
- Fixed Robot common.resource path to ${CURDIR}/common.resource (hurui200320 L1)
- Squashed all commits into one and rebased onto master (C1, C2)
- Added CHANGELOG entry with correct scenario count
Closes#537
