feat: writing cohesion rubric + samples list CLI + batch CSV export (Fixes #66, #59, #32)

[laurentketterle-hub]

Summary

Writing cohesion/coherence rubric, samples list CLI, and batch CSV export for NokaMan.

Changes

Writing cohesion/coherence rubric (Fixes #66):

• New writing_cohesion.py module with 4 offline dimensions:
  • Cohesion (pronoun/connective density, lexical variety)
  • Coherence (sentence flow, paragraph connection)
  • Paragraph structure (topic sentences, length balance)
  • Transition quality (sentence-starting transition words)
• score_writing_cohesion() and score_writing_sample() functions
• Deterministic surface-level heuristics (no network/LLM required)

CLI samples list (Fixes #59):

• New nokaman samples list command
• Optional --language / -l and --skill / -s filters
• Rich table with file, language, skill, and text preview columns

Batch CSV export (Fixes #32):

• Added --format csv / -f csv option to nokaman eval batch
• Exports results as CSV: file, language, skill, score, cefr, expected_cefr, distance

Tests

• 9 new tests in test_writing_cohesion.py — all passing (75/75 total)
• All existing tests continue to pass

Fixes #66, Fixes #59, Fixes #32
