feat: improve TS/Hono architecture guidance and add Effect CLI profile

[soulcodex]

Why

This PR tightens our TypeScript-first guidance for API and CLI projects so generated AGENTS instructions are more consistent with hexagonal boundaries and domain-driven error handling.

The main gaps addressed were:

• Hono usage was implicit in profiles but not represented as an explicit framework fragment with concrete controller patterns.
• Domain logic placement rules were present but not strong enough to prevent business rules from drifting into helpers/adapters.
• TypeScript CLI guidance lacked an Effect-based profile aligned with ports-and-adapters.
• Error guidance did not consistently push typed, domain-specific errors and reusable IsXxxError / isXxxError helpers.
• TypeScript runtime targets were behind the current Node LTS line.

What Changed

1) New framework fragments

• Added agents/frameworks/hono.md
  • Class-based controllers
  • register(app: Hono)-style semantic route registration
  • Typed/validated params at the boundary
  • Centralized domain-to-HTTP error mapping
  • Middleware DI guidance: external deps are created in composition root and injected as handlers/factories
• Added agents/frameworks/effect-cli.md
  • @effect/cli + @effect/platform-node command patterns
  • Thin command handlers as adapters
  • Composition-root layer wiring
  • Typed error-to-exit/output mapping

2) Stronger architecture and language rules

• Updated agents/architecture/hexagonal.md
  • Added explicit rule to keep business rules cohesive and out of scattered utility functions
• Updated agents/languages/typescript.md
  • Prefer domain/application custom errors over generic Error for business failures
  • Add/reuse isXxxError helpers for branching
  • Explicit DI rule for middleware with infra dependencies (Redis/SDK/config)
• Updated agents/languages/go.md
  • Prefer custom domain errors for business failures
  • Add/reuse IsXxxError(err) helpers to centralize errors.Is/errors.As logic

3) New TypeScript Effect CLI profile

• Added profiles/typescript-hexagonal-effect-cli.yaml
  • @effect/cli + @effect/platform-node
  • Hexagonal + DDD composition
  • pnpm + Node 24+

4) Hono explicitly declared in TS hexagonal backend profiles

• Updated TypeScript hexagonal backend/fullstack profiles to include framework: hono where backend fragments are declared.

5) Node runtime alignment (TypeScript profiles)

• Updated TypeScript profile runtime metadata from Node 22+ / Node.js 20+ to Node 24+ (current LTS line).

6) Essential docs/index updates

• Updated docs/profiles.md to include the new TypeScript Effect CLI profile
• Regenerated index/fragments.json

Scope Notes

• No README.md changes (intentionally, per request).
• This PR updates configuration guidance and profile metadata only; no runtime application code is changed.

Validation

• just lint
• just index

Reviewer Checklist

• Confirm new fragments are self-contained and follow heading/size rules
• Confirm new profile validates against profile schema
• Confirm TS profile runtime updates are consistent across all TypeScript profiles
• Confirm docs/profiles.md and index/fragments.json reflect the new profile/fragments

Follow-up (Optional)

• Align Node runtime strings in mixed Go + frontend profiles to Node 24+ for full cross-profile consistency.
