Add engineering design skills under .cursor/skills

[dipanshuhappy]

Summary

Adds four repo-scoped engineering/design skills as SKILL.md files under .cursor/skills/, each with standard name + description frontmatter so Cursor agents working in this repo can discover and apply them.

These are general engineering-philosophy skills for developing this SDK monorepo — distinct from the Caspian product skills that ship inside the OpenCode plugin (packages/opencode/src/skills/). The four skills cross-reference each other (functional-dsl, languages-as-libraries, meta-minimal-languages), so the directory names match those references.

Skills added

Path	Skill
.cursor/skills/sdk-reliability/SKILL.md	SDK & Dev Tools Reliability — 10X reliability framework (fault / capacity / change; critical-path discipline)
.cursor/skills/meta-minimal-languages/SKILL.md	Meta-Minimal Languages — keep the core small/stable, let layered libraries evolve as "languages"
.cursor/skills/languages-as-libraries/SKILL.md	Languages as Libraries — ship dialects/typed layers over a host toolchain without forking the compiler
.cursor/skills/functional-dsl/SKILL.md	Functional DSLs — algebra/denotation-first DSL design; effects isolated to interpreters

Notes

• Documentation-only change; no application code touched.
• Each file preserves the provided content verbatim, formatted as Markdown with YAML frontmatter matching the existing SKILL.md convention in the repo.
