Remove explicit correction commands

[masa10-f]

Summary

Closes #200.

This removes explicit X and Z correction commands from measurement patterns and keeps output corrections in PauliFrame.

Changes

• Remove graphqomb.command.X and graphqomb.command.Z from the command API.
• Stop emitting terminal correction commands for unmeasured outputs in qompile().
• Apply pending output Pauli-frame corrections in PatternSimulator before returning output statevectors or explicit output measurement results.
• Store explicit output measurement results in PatternSimulator.output_results, keyed by logical output index.
• Reject legacy .ptn X/Z command lines as unknown commands.
• Update Stim compiler handling, docs, changelog, and regression tests.

Validation

• uv run pytest -q
• uv run ruff check graphqomb tests
• uv run ruff format --check graphqomb tests
• uv run --extra dev pyright
• uv run --extra doc sphinx-build -b html docs/source docs/build/html
