[workshop-diagrams] Add theme-aware brand-compliant diagram for resilience techniques

[github-actions]

Summary

Migrates the existing explanatory diagram in workshop/22-error-handling-and-resilience.md from a non-brand palette to the GitHub-inspired workshop brand palette.

What changed

Workshop file: workshop/22-error-handling-and-resilience.md — no Markdown changes needed; the <picture> block was already correctly structured.

SVG files migrated:

• workshop/images/22-resilience-techniques-light.svg
• workshop/images/22-resilience-techniques-dark.svg

Change type

Migration of an existing explanatory diagram (not a new concept).

What changed in the SVGs

• Palette: Replaced GitHub.com Primer colors with the workshop brand palette — neutral backgrounds (#f2f5f3 light / #101411 dark), Green 5 accent (#08872b light / #5fed83 dark), Gray 3/4 borders
• Typography: Updated to Mona Sans / Mona Sans Mono with system-sans fallbacks
• Icons: Replaced emoji characters with geometric SVG paths (warning triangle, shield, clock, output arrow, checkmark circle)
• **Semantic meta(redacted) Added data-visual-kind="diagram", data-visual-id, and data-node attributes on all diagram nodes
• Script check: scripts/check-svg-visual-language.js reports zero violations
• Playwright QA: Light and dark currentSrc selections verified; screenshots nonblank

Why this helps learners

The diagram maps four common agentic workflow failure modes (prompt drift, timeout, tool error, empty data) to three practical mitigations (defensive brief, timeout-minutes, fallback safe-output). Upgrading to the brand palette makes it visually consistent with other workshop materials and ensures the semantic metadata contract required by automated diagram QA is satisfied.
