Release v0.8.0 — bump pipelex to 0.26.4

[lchoquel]

Summary

• Bump pipelex from >=0.18.1 to >=0.26.4 (and lock).
• Add pipelex-tools>=0.3.2 dev dependency.
• Update tests/integration/conftest.py to the new needs_inference kwarg on Pipelex.make() (the old disable_inference was removed upstream and was breaking make test).
• Add .pipelex/traces to .gitignore (runtime artifacts).
• Restore CHANGELOG.md with a v0.8.0 entry — required by .github/workflows/changelog-check.yml.

Test plan

• make test passes locally
• CI green on PR

Greptile Summary

Bumps the pipelex runtime dependency from >=0.18.1 to >=0.26.4, adds pipelex-tools>=0.3.2 as a dev dependency, and migrates the integration test fixture to the new upstream API.

• pyproject.toml: version → 0.8.0, pipelex lower-bound raised to 0.26.4, pipelex-tools added to the dev extras group.
• tests/integration/conftest.py: disable_inference=is_inference_disabled_in_pipelex(request) replaced with the semantically complementary needs_inference=needs_inference_in_pipelex(request) to match the renamed upstream kwarg.
• .gitignore / CHANGELOG.md: .pipelex/traces excluded from version control; CHANGELOG.md created with a v0.8.0 entry required by the CI workflow.

Confidence Score: 5/5

All changes are mechanical dependency bumps and a one-for-one API rename; no logic changes outside the test fixture migration.

The only behavioural change is swapping disable_inference for needs_inference in the test fixture. The two helper functions (is_inference_disabled_in_pipelex → needs_inference_in_pipelex) are semantically complementary, so the test configuration intent is preserved. The rest of the diff is lock-file generation, gitignore hygiene, and a new CHANGELOG entry.

No files require special attention.

Important Files Changed

Filename	Overview
tests/integration/conftest.py	Migrates from deprecated disable_inference / is_inference_disabled_in_pipelex to the new needs_inference / needs_inference_in_pipelex API; semantics are correctly complementary.
pyproject.toml	Version bumped to 0.8.0, pipelex lower-bound raised to 0.26.4, pipelex-tools added to dev extras; all changes are consistent with each other.
.gitignore	Adds .pipelex/traces alongside the existing .pipelex/storage exclusion; straightforward and correct.
CHANGELOG.md	New file created to satisfy the CI changelog-check workflow; entry accurately describes all changes in this release.
uv.lock	Lock file regenerated to reflect new dependencies (pipelex 0.26.4, pipelex-tools 0.3.2 and their transitive deps like black, cffi, argcomplete); appears complete and consistent.
