Allow inject to compose with parameterize

[Probablism]

Fixes #160.

This updates expander resolution so @inject can run before regular expanders such as @parameterize. That lets an injected dependency be available when the parameterized function variants are created.

Changes

• Add a pre-expander pass for expanders that need to run before regular node expansion.
• Mark @inject as a pre-expander while keeping the existing single regular expander restriction.
• Validate that injected target parameters do not overlap with parameters consumed by regular parameterization.
• Add regression coverage for both decorator orders and the overlapping-parameter failure case.

How I tested this

• tests/function_modifiers/test_expanders.py passed locally.
• The main package test suite passed locally: 1446 passed, 5 skipped, 2 xpassed.
• Static lint/format checks passed locally.
• Fork GitHub Actions Unit Tests passed on fix-inject-parameterize across Python 3.10 through 3.14.

Notes

• No user-facing documentation changes were needed; this is a decorator composition bug fix.
