fix(docs): rewrite 270 broken internal markdown links after subfolder restructure

The FASE 3 /docs restructure moved files into 8 subfolders (architecture,
guides, reference, frameworks, routing, security, compression, ops) but left
several link categories with stale relative paths. The new check:doc-links
gate (FASE 8) surfaced these and produced this exhaustive fix sweep.

Categories repaired (counts before → after, total broken: 270 → 0):

  i18n-relative (241 → 0): docs in subfolders now reference translations
    under docs/i18n/<locale>/docs/<subfolder>/<FILE>.md (one extra "../"
    plus the docs/<subfolder>/ segment). Affects ARCHITECTURE, FEATURES,
    USER_GUIDE, TROUBLESHOOTING, UNINSTALL, VM_DEPLOYMENT_GUIDE,
    API_REFERENCE, and the I18N.md self-reference table.

  parent-relative (14 → 0): refs like ../CLAUDE.md, ../CONTRIBUTING.md,
    ../AGENTS.md, ../Tuto_Qdrant.md, ../open-sse/..., ../electron/...,
    ../src/... promoted from one to two parent hops (../ → ../../) to
    reach repo root from docs/<subfolder>/.

  screenshots (9 → 0): FEATURES.md PNG refs rewritten to ../screenshots/
    (assets live at docs/screenshots/ unchanged).

  missing-rfc (2 → 0): RFC-AUTO-ASSESSMENT.md was deleted earlier in the
    overhaul; replaced refs in EVALS.md with pointers to the live
    AUTO-COMBO.md scoring doc plus an in-prose mention of
    src/domain/assessment/.

  other (4 → 0): ENVIRONMENT.md → ../../.env.example,
    SETUP_GUIDE.md → ../../{open-sse/mcp-server,src/lib/a2a}/README.md,
    PROVIDER_REFERENCE.md → ../../src/shared/... and ../../open-sse/...,
    VM_DEPLOYMENT_GUIDE.md omnirouteCloud reference replaced with a
    pointer to in-repo TUNNELS_GUIDE.md (omnirouteCloud lives in a
    separate companion repo).

Validation:
  npm run check:doc-links → PASS (501 internal links, 0 broken)
