feat(context): Context Engineering Configurator + consolidated guide (v3.34.0)

New: interactive configurator at cc.bruniaux.com/context/ that generates a
personalized CLAUDE.md starter kit based on team size, stack, and current setup.
Multi-step flow (profile, current state, stack, results) with maturity scoring
(Level 1-5), copy-to-clipboard artifacts, localStorage persistence.

Guide content:
- guide/core/context-engineering.md (1,188 lines, 8 sections): context budget,
  150-instruction ceiling, modular architecture, team assembly, ACE pipeline,
  quality measurement, context reduction techniques
- examples/context-engineering/ (10 templates): assembler.ts, profile-template.yaml,
  skeleton-template.md, canary-check.sh, ci-drift-check.yml, eval-questions.yaml,
  context-budget-calculator.sh, rules/knowledge-feeding.md, rules/update-loop-retro.md
- tools/context-audit-prompt.md (543 lines): 8-dimension scoring /100

Navigation: guide/README.md, machine-readable/reference.yaml (24 new entries)
