refactor(skills): update dspy-ruby skill to DSPy.rb v0.34.3 API (#162)

Rewrite all reference files, asset templates, and SKILL.md to use
current API patterns (.call(), result.field, T::Enum classes,
Tools::Base). Add two new reference files (toolsets, observability)
covering tools DSL, event system, and Langfuse integration.

+# Update dspy-ruby Skill to DSPy.rb v0.34.3 API
+
+## Problem
+
+The `dspy-ruby` skill uses outdated API patterns (`.forward()`, `result[:field]`, inline `T.enum([...])`, `DSPy::Tool`) and is missing 10+ features (events, lifecycle callbacks, GEPA, evaluation framework, BAML/TOON, storage, etc.).
+
+## Solution
+
+Use the engineering skill as base (already has correct API), enhance with official docs content, rewrite all reference files and templates.
+
+### Source Priority (when conflicts arise)
+
+1. **Official docs** (`../dspy.rb/docs/src/`) — source of truth for API correctness
+2. **Engineering skill** (`../engineering/.../dspy-rb/SKILL.md`) — source of truth for structure/style
+3. **NavigationContext brainstorm** — for Typed Context pattern only
+
+## Files to Update
+
+### Core (SKILL.md)
+
+1. **`skills/dspy-ruby/SKILL.md`** — Copy from engineering base, then:
+   - Fix frontmatter: `name: dspy-rb` → `name: dspy-ruby`, keep long description format
+   - Add sections before "Guidelines for Claude": Events System, Lifecycle Callbacks, Fiber-Local LM Context, Evaluation Framework, GEPA Optimization, Typed Context Pattern, Schema Formats (BAML/TOON)
+   - Update Resources section with 5 references + 3 assets using markdown links
+   - Fix any backtick references to markdown link format
+
+### References (rewrite from themed doc batches)
+
+2. **`references/core-concepts.md`** — Rewrite
+   - Source: `core-concepts/signatures.md`, `modules.md`, `predictors.md`, `advanced/complex-types.md`
+   - Cover: signatures (Date/Time types, T::Enum, defaults, field descriptions, BAML/TOON, recursive types), modules (.call() API, lifecycle callbacks, instruction update contract), predictors (all 4 types, concurrent predictions), type system (discriminators, union types)
+
+3. **`references/toolsets.md`** — NEW
+   - Source: `core-concepts/toolsets.md`, `toolsets-guide.md`
+   - Cover: Tools::Base, Tools::Toolset DSL, type safety with Sorbet sigs, schema generation, built-in toolsets, testing
+
+4. **`references/providers.md`** — Rewrite
+   - Source: `llms.txt.erb`, engineering SKILL.md, `core-concepts/module-runtime-context.md`
+   - Cover: per-provider adapters, RubyLLM unified adapter, Rails initializer, fiber-local LM context (`DSPy.with_lm`), feature-flagged model selection, compatibility matrix
+
+5. **`references/optimization.md`** — Rewrite
+   - Source: `optimization/miprov2.md`, `gepa.md`, `evaluation.md`, `production/storage.md`
+   - Cover: MIPROv2 (dspy-miprov2 gem, AutoMode presets), GEPA (dspy-gepa gem, feedback maps), Evaluation (DSPy::Evals, built-in metrics, DSPy::Example), Storage (ProgramStorage)
+
+6. **`references/observability.md`** — NEW
+   - Source: `production/observability.md`, `core-concepts/events.md`, `advanced/observability-interception.md`
+   - Cover: event system (module-scoped + global), dspy-o11y gems, Langfuse (env vars), score reporting (DSPy.score()), observation types, DSPy::Context.with_span
+
+### Assets (rewrite to current API)
+
+7. **`assets/signature-template.rb`** — T::Enum classes, `description:` kwarg, Date/Time types, defaults, union types, `.call()` / `result.field` usage examples
+
+8. **`assets/module-template.rb`** — `.call()` API, `result.field`, Tools::Base, lifecycle callbacks, `DSPy.with_lm`, `configure_predictor`
+
+9. **`assets/config-template.rb`** — RubyLLM adapter, `structured_outputs: true`, `after_initialize` Rails pattern, dspy-o11y env vars, feature-flagged model selection
+
+### Metadata
+
+10. **`.claude-plugin/plugin.json`** — Version `2.31.0` → `2.31.1`
+
+11. **`CHANGELOG.md`** — Add `[2.31.1] - 2026-02-09` entry under `### Changed`
+
+## Verification
+
+```bash
+# No old API patterns
+grep -n '\.forward(\|result\[:\|T\.enum(\[\|DSPy::Tool[^s]' plugins/compound-engineering/skills/dspy-ruby/SKILL.md
+
+# No backtick references
+grep -E '`(references|assets|scripts)/' plugins/compound-engineering/skills/dspy-ruby/SKILL.md
+
+# Frontmatter correct
+head -4 plugins/compound-engineering/skills/dspy-ruby/SKILL.md
+
+# JSON valid
+cat plugins/compound-engineering/.claude-plugin/plugin.json | jq .
+
+# All files exist
+ls plugins/compound-engineering/skills/dspy-ruby/{references,assets}/
+```
+
+## Success Criteria
+
+- [x] All API patterns updated (`.call()`, `result.field`, `T::Enum`, `Tools::Base`)
+- [x] New features covered: events, callbacks, fiber-local LM, GEPA, evals, BAML/TOON, storage, score API, RubyLLM, typed context
