…es (#733)

## Summary

- Fixes #732 - "Canonicalized path was dropped" error that could occur in CI environments
- Ensures canonicalized paths have at least one strong reference in the cache to prevent premature dropping
- Adds comprehensive tests to prevent regression

## Problem

The resolver was experiencing "Canonicalized path was dropped" errors due to weak references being used without ensuring a strong reference existed. When `canonicalize_impl` stored only weak references to canonicalized paths, if those paths weren't already in the cache, the Arc would be immediately dropped, causing the weak reference to fail on upgrade.

## Solution

Modified `canonicalize_impl` in `src/cache/cache_impl.rs` to ensure canonicalized paths are added to the cache (if not already present) before downgrading to weak references. This maintains at least one strong reference while preserving the weak reference pattern needed to avoid memory leaks from circular references.

## Test Plan

- [x] Added `test_canonicalized_path_not_dropped` to verify canonicalization works correctly
- [x] Added `test_canonicalized_path_weak_reference` to ensure the error doesn't occur
- [x] All existing tests pass, including the memory leak test
- [x] `cargo test` passes
- [x] `cargo clippy` passes
- [x] `cargo check` passes

--- failure constructible_struct_adds_field: externally-constructible struct adds field ---

Description:
A pub struct constructible with a struct literal has a new pub field. Existing struct literals must be updated to include the new field.
