CTX7-2006: Support on-premise setup in ctx7 CLI

[fahreddinozcan]

Summary

• add custom deployment support to ctx7 setup --mcp --base-url
• discover on-prem MCP auth and generate anonymous or Authorization bearer configuration for every supported client
• securely prompt for an on-prem personal key with masked input when auth is enabled, while preserving --api-key and CONTEXT7_API_KEY for automation
• make custom-deployment setup outbound-independent after the CLI is installed: no npm update check, telemetry, GitHub, Context7 Cloud, or remote rule/skill fetch
• bundle MCP rules and skills, resolve the deployment once, and pass only the final MCP endpoint to agent builders
• document public or approved internal-registry installation for restricted and air-gapped environments
• add a ctx7 changeset

Testing

• pnpm --filter ctx7 typecheck
• pnpm --filter ctx7 lint:check
• pnpm --filter ctx7 test (263 tests)
• pnpm --filter ctx7 build
• real built-CLI to local on-prem E2E with a masked interactive key prompt
• verified generated bearer config, bundled rule/skill installation, non-interactive --yes behavior, and cleanup
