deps: bump decimal to 3.1

[DaemonSnake]

Decimal v3 applies decimal128 parse limits (34 digits, exp ±6144) via Decimal.new/1, which raises on large Postgres numeric values. Parse with max_digits/max_exponent: :infinity to keep arbitrary-precision casting.

Pulls postgrex 0.22.2, whose constraint allows decimal ~> 3.0.

Summary by CodeRabbit

• Improvements

  • Centralized decimal parsing options for more consistent and reliable handling of PostgreSQL numeric and money values, including single values and arrays.

• Chores

  • Bumped Decimal dependency from ~> 2.3.0 to ~> 3.1 (override enabled).

📝 Walkthrough

Walkthrough

WalEx centralizes Decimal parsing options via a module attribute and applies unbounded-precision options across numeric, money, and array casting paths. The :decimal dependency is upgraded to ~> 3.1 with override: true.

Changes

Decimal Arbitrary-Precision Support

Layer / File(s)	Summary
Decimal precision configuration and dependency upgrade lib/walex/casting/types.ex, mix.exs	@decimal_opts module attribute configures Decimal.new/2 with unbounded max_digits and max_exponent. The :decimal dependency is upgraded from ~> 2.3.0 to ~> 3.1 with override: true.
Apply decimal options across casting paths lib/walex/casting/types.ex	PostgreSQL casts for "numeric", "money", "_numeric", and "_money" now use Decimal.new(value, @decimal_opts) (or the appropriate two-argument form) instead of the default Decimal.new/1 to preserve arbitrary precision.

Poem

🐰 With tiny paws I tweak the code tonight,

decimals unbound, every digit bright.
From numeric fields to money arrays,
I hop through digits in joyful craze.
Precision preserved — a rabbit's delight.
