Preserve attribution in inverted dependency trees

[zanieb]

Summary

Preserve dependency provenance when rendering inverted project trees.

Inverted traversal now carries required extras and universal marker conditions through each reverse path, stops dependency-group paths at the workspace member that owns the group, and rejects consumers that did not activate the required extra. Declared conflict constraints are included when checking marker satisfiability, so mutually exclusive extras and groups cannot form an impossible path through a shared package node.

This prevents uv tree --invert from attributing an optional, grouped, or marker-conditional dependency to unrelated workspace members.

Test Plan

• cargo +stable test --package uv --test project tree
• cargo +stable clippy --package uv-resolver --all-targets --all-features --locked -- -D warnings
• cargo +stable clippy --package uv --test project --locked -- -D warnings
• cargo +stable fmt --all -- --check
• git diff --check
