Run Aqua in tests; fix Bool conversions and rounding

[ViralBShah]

Running Aqua on master reports two problems: a method ambiguity between the generic (::Type{I<:Integer})(x::DecimalFloatingPoint) constructor and Base.Bool(::Real), and a missing [compat] entry for Test.

Fixing the ambiguity surfaced a few related pre-existing Bool bugs:

• Dec64(true) fell through to the string-parsing fallback and threw ArgumentError: invalid number format true.
• trunc(Bool, x) / floor / ceil / round(Bool, x) were ambiguous with Base's (::Type{Bool}, ::AbstractFloat) methods on Julia < 1.11, and on 1.11+ they hit the generic integer path which constructs I(10) and throws InexactError: Bool(10).

Changes:

• Base.Bool(x::DecimalFloatingPoint) with the same semantics as Bool(::Real).
• DecXX(x::Bool) routed through the existing Int32 constructor.
• trunc/floor/ceil/round(::Type{Bool}, x) defined via Int.
• Test = "<0.0.1, 1" compat; Aqua added to the test target and Aqua.test_all run in runtests.jl.

Tested locally on Julia 1.7 (x64), 1.9, 1.10 and 1.12; all pass including all 11 Aqua checks.
