chore: remove LinkedIn MCP server

[xnoto]

Summary

Remove the unused local mcp-server-linkedin definition from the canonical OpenCode configuration.

Fixes: no issue.

Type of change

• Refactor / cleanup
• Bug fix
• Feature / enhancement
• Documentation
• Infrastructure (OpenTofu root or module)
• GitOps desired state (manifests, kustomize, charts, SOPS/KSOPS secrets)
• Container image
• CI / reusable workflow
• Breaking change

Validation

• Required pull-request checks pass
• Reviewed the PR diff: only the LinkedIn MCP configuration is removed.
• Generated or centrally distributed files were not hand-edited.

Impact and rollout

Canonical source: xnoto/opencode-config (~/.config/opencode chezmoi Git external). xnoto/dotfiles only maps this external and xnoto/mcp-gateway has no LinkedIn server entry, so neither changes. Existing installations will retain the entry until their normal external update and configuration reload; no workstation action was performed.

Safety and secrets

• Contains no plaintext secrets, decrypted SOPS values, state files, kubeconfigs, tokens, or private endpoints
• No local OpenTofu init/plan/apply/destroy/import/state operations were run or claimed — plans come from pull-request checks
• No breaking or irreversible effects beyond removing the unused MCP definition; revert restores it.
