test(validation): property-based tests for template expansion (B4.1)

[JarbasAl]

Adds hypothesis property tests for expand_template — the core of intent/vocab validation — asserting invariants that must hold for any well-formed template, not just examples:

• plain text expands to exactly its normalized self
• every {slot} is preserved in every expansion
• no group delimiters ()[] remain in output
• expansion is idempotent on already-expanded lines
• (a|b|c) yields exactly one line per distinct alternative
• a [b] yields both the with- and without-optional forms

Declares hypothesis>=6.0 as a dev dependency.

Local: pytest test/unittests/test_bracket_expansion_properties.py → 6 passed.
