refactor(jwks): multi-sink output via view Doc and JSON

[xenOs76]

Separate collect from present with a typed Result, render console through internal/view Doc, and add --format json for agents/MCP. Synchronize allowedCLICommands format flag in MCP tools.

Summary by CodeRabbit

• New Features

  • Added JSON output support for the JWKS command via --format json.
  • JSON responses include schema metadata and generated keys without terminal styling codes.
  • Added --format support for JWKS, JWT information, and request commands in MCP integrations.
  • Improved formatted console rendering for JWKS text output.

• Bug Fixes

  • Unsupported output formats now return an error and exit with status 1.

• Tests

  • Expanded coverage for JSON, text rendering, validation, and MCP command generation.

📝 Walkthrough

Walkthrough

The JWKS package now returns structured results for JSON envelopes and RFC 7517 output. The CLI adds --format text|json, text rendering through view.Doc, and JSON output. MCP handling and integration tests validate the format.

Changes

JWKS output flow

Layer / File(s)	Summary
Structured JWKS result internal/jwks/jwks.go, internal/jwks/result.go, internal/jwks/*_test.go	Adds Result, JSON encoders, Generate, nil guards, and tests for structured JWKS data. GenerateJWKS now delegates to the structured result.
CLI format handling internal/cmd/jwks.go, internal/cmd/jwks_test.go, internal/jwks/view.go, internal/jwks/view_test.go	Adds --format text|json, validates values, renders text through view.Render, writes JSON envelopes, and verifies unsupported-format exit status.
MCP format integration internal/mcp/tools.go, internal/mcp/tools_exec.go, internal/mcp/*_test.go	Allows format flags for MCP command construction and encodes generate_jwks results with the JWKS JSON envelope.
Integration validation and changelog devenv.nix, CHANGELOG.md	Adds a devenv check for JWKS JSON fields and ANSI-free output. Records the JWKS feature and related next steps.

Merge Risk: ⚪ Minimal · up to ebf77

The JWKS command supports the documented text and JSON outputs, rejects unsupported formats with a failing exit status, and MCP returns the expected JSON envelope. No actionable merge risk remains.

In `@internal/cmd/jwks.go`:
- Line 46: Change the JWKS command handler from Run to RunE and return an error
when jwksFmt is unsupported instead of only printing it, so command execution
fails with a non-nil error and status 1. Preserve the existing valid text and
json behavior, and add an execution-level test covering the unsupported format
and failed exit behavior.
