Confusing error messages on package resolution failure

[zanieb]

This issue is to collect all confusing error messages on package resolution failure.

Upstream issues:

• Allow an arbitrary, custom incompatibilities pubgrub-rs/pubgrub#152
• Dependency version with invalid direct dependencies should be tracked as incompatibility pubgrub-rs/pubgrub#151
• Root package version should be optional pubgrub-rs/pubgrub#150
• Error reporting: Repeated direct dependency with incompatible versions pubgrub-rs/pubgrub#149

# example.in
httpx==0.8.0
httpx==0.9.0

$ cargo run -p puffin-cli -- pip-compile example.in
  × No solution found when resolving dependencies:
  ╰─▶ root depends on httpx ∅

Two incompatible versions of the same package results in a useless error

[zanieb]

# example.in
httpx==0.8.0
h2==0.3.21

$ cargo run -p puffin-cli -- pip-compile example.in
  × No solution found when resolving dependencies:
  ╰─▶ Because httpx 0.8.0 depends on h2 >=3.dev0, <4.dev0 and root depends on h2 0.3.21, root, httpx 0.8.0 are incompatible.
      And because root depends on httpx 0.8.0, root is forbidden.

A pinned incompatible version of an indirect requirement.

This one is relatively reasonable? It's just quite verbose. We need to do better on root is forbidden cases.

[charliermarsh]

# example.in
werkzeug==7.0.0

This version doesn't exist, so you get:

$ cargo run -p puffin-cli -- pip-compile requirements.in --verbose --no-cache
  × No solution found when resolving dependencies:
  ╰─▶ root depends on werkzeug 7.0.0

The lack of version range merging makes this one unreadable:

cargo run --bin puffin -q -- pip-compile scripts/benchmarks/requirements/pydantic_all.in 
  × No solution found when resolving dependencies:

The requirements are using pydantic-extra-types @ git+https://github.com/pydantic/pydantic-extra-types.git@main, which means there is actually only one version possible.

Compared to the pip error:

ERROR: Cannot install pydantic-core==2.11.0 and pydantic-extra-types because these package versions have conflicting dependencies.

The conflict is caused by:
