Add ./roe-cli format, lint CI gate, and format codebase

[jadenfix]

Summary

• Add ./roe-cli with a format command (ruff format + ruff check --fix), mirroring roe-main's ./roe-cli format
• Add a dedicated lint CI job (ruff check + ruff format --check) that runs on every PR and on pushes to main
• Make scripts/generate-sdk ruff-format generated wrappers (src/roe/api) so running the formatter never introduces codegen drift (ruff added to the codegen dependency group)
• Document ./roe-cli format in the README (Development section)
• Format the codebase with ruff format (9 files)

Test plan

• ./roe-cli format then ruff format --check . and ruff check . → clean
• uv run pytest → 39 passed
• bash scripts/generate-sdk then drift diff on the CI-checked paths → clean

Greptile Summary

This PR introduces a ./roe-cli format developer script, a dedicated CI lint job (ruff check + ruff format --check), and formats the existing codebase with ruff. It also extends scripts/generate-sdk to run ruff format on the generated wrappers so codegen never introduces formatting drift.

• CI: The old single-step ruff check lint is replaced by two explicit steps (--output-format=github and --check --diff) in a new lint job; the test job is left independent (no needs: gate), so both run in parallel on every PR.
• Tooling: roe-cli is a new bash script with a format command that runs ruff check --fix then ruff format; ruff is added to the codegen dependency group so generate-sdk can invoke it.
• Code changes: All source and example file changes are pure ruff-formatting reformats with no logic modifications.

Confidence Score: 5/5

Safe to merge — all source changes are pure reformats with no logic modifications, and the new tooling is additive.

Every change to src/ and examples/ is a line-wrapping reformat only. The new roe-cli, CI lint job, and codegen formatting step are straightforward additions that don't touch runtime behaviour. The one UX quirk in roe-cli (format step skipped when unfixable lint errors exist) doesn't affect correctness or CI.

No files require special attention; the only non-trivial new file is roe-cli.

Important Files Changed

Filename	Overview
.github/workflows/ci.yml	Splits the original single job into separate lint and test jobs; both are independent (no needs: relationship), which is fine. Lint now uses --output-format=github and --diff for better PR annotations.
roe-cli	New bash CLI script; correctly orders ruff check --fix before ruff format, but set -e causes the format step to be skipped entirely when there are unfixable lint violations.
scripts/generate-sdk	Adds ruff format on src/roe/api after wrapper generation to prevent codegen drift when the formatter is run.
pyproject.toml	Adds ruff to the codegen dependency group so generate-sdk can invoke it; ruff was already present in the dev group.
scripts/generate_wrappers.py	Pure ruff formatting reformats (line-wrapping only), no logic changes.
src/roe/config.py	Pure formatting change to batch_chunk_delay assignment; logic is identical.
src/roe/exceptions.py	Pure formatting change to translate_response raise statement; no logic change.
src/roe/models/job.py	Pure formatting changes to ternary and list comprehension; no logic change.
src/roe/utils/transport.py	Pure formatting change to conditional; no logic change.
src/roe/api/agents.py	Pure formatting change to AgentRunAsyncManyRequest instantiation; no logic change.
