chore: fix ruff violations F841, F811, E741 in main.py

[Copilot]

Three ruff-detected code quality violations in main.py that were flagged by the automated code quality agent.

Changes

• F841 — Drop unused binding e from a bare-reraise handler:

  # before
  except httpx.HTTPStatusError as e:
      raise
  # after
  except httpx.HTTPStatusError:
      raise

• F811 + E741 — Remove the second, never-called print_summary_table definition (formerly ~lines 2358–2397). It shadowed the primary definition at line 316 and was dead code — the summary table is rendered inline in main(). The removed block also contained an inner helper def line(l, m, r) whose l parameter triggered E741 (ambiguous name, visually indistinguishable from 1).

Pull request overview

Cleans up ruff-reported lint issues in main.py (unused exception binding and duplicate function definition) and updates the Python dependency lockfile to reflect dev dependencies.

Changes:

• Remove unused exception binding in _gh_get (except httpx.HTTPStatusError as e → except httpx.HTTPStatusError).
• Delete the duplicate (shadowing) print_summary_table definition near the entry-point section.
• Update uv.lock to include pytest-benchmark (and transitive py-cpuinfo) under dev dependencies.

File	Description
main.py	Fixes ruff violations by removing an unused exception binding and deleting a duplicate dead-code function definition.
uv.lock	Brings the lockfile in sync with dev dependencies by adding pytest-benchmark and py-cpuinfo.

[Copilot]

This comment is contradictory: it says “don't catch and re-raise”, but the code is explicitly catching HTTPStatusError and re-raising it. Consider rewording to clarify the intent (e.g., that the exception is intentionally propagated unchanged / without wrapping).

Suggested change

	# Re-raise with original exception (don't catch and re-raise)
	# Intentionally propagate HTTPStatusError unchanged (no wrapping or swallowing)
