# Task 58: Remove `from __future__ import annotations` From All Code

## Problem

`from __future__ import annotations` is used throughout the codebase but is unnecessary for Python 3.10+ (which is our minimum version). It adds noise to every file.

## Implementation

1. Remove `from __future__ import annotations` from all `.py` files in `src/` and `tests/`
2. Fix any type annotations that break without it (e.g. `X | Y` union syntax works natively in 3.10+, but forward references as strings may need updating)
3. Run full test suite to verify no regressions

## Acceptance Criteria

- [x] No file in `src/` or `tests/` contains `from __future__ import annotations`
- [x] All tests pass
- [x] Lint passes

## Methodology

Bulk removal + test run. No TDD needed — this is a mechanical cleanup.

## Dependencies

None.

## Estimated Complexity

Low — search and replace, then fix any breakage.
