feat(whoami): show linked application and add --json output

[rafa-thayto]

Summary

• clerk whoami now prints a Linked to MyApp (app_xxx) line on stderr above the next-steps when the working directory is linked to a Clerk application — preserving stdout-as-email so existing pipes (e.g. clerk whoami | grep @) keep working.
• New --json flag (and matching agent-mode auto-JSON) emits a structured payload on stdout covering email and link state, including normalized nulls for missing optional fields.
• Adds a tiny profileLabel(profile) helper in lib/config.ts mirroring appLabel(app) from lib/app-picker.ts, so the local Profile shape and the live Application shape have parallel display formatters.

Stacked on #250. Base is rafa-thayto/more-next-steps. GitHub will auto-rebase this onto main when #250 merges. Diff against this PR's base is the whoami-only delta.

JSON shape

{
  "email": "alice@example.com",
  "linked": {
    "appId": "app_xxx",
    "appName": "MyApp",
    "instances": { "development": "ins_dev_xxx", "production": "ins_prod_xxx" },
    "resolvedVia": "remote",
    "path": "github.com/clerk/cli"
  }
}

linked is null when not linked or when profile resolution throws (best-effort path preserved from #250's commit `1652c122`).

Test plan

• `bun run format && bun run lint && bun run typecheck && bun run test` (all green locally — 97 test files)
• `bun test packages/cli-core/src/commands/whoami/index.test.ts` (11 cases: 3 prior auth paths + 4 new human-mode + 4 new JSON/agent)
• Manual smoke — linked path: `clerk whoami` shows email on stdout, "Linked to ..." on stderr, next-steps follow
• Manual smoke — `clerk whoami --json` emits a single JSON object on stdout, no next-steps
• Manual smoke — unlinked path (fresh `/tmp` directory): no "Linked to" line
• Pipe contract: `clerk whoami | grep @` returns just the email
• `bun changeset status --since=origin/main` exits 0 (changeset `whoami-linked.md` written, `clerk: minor`)

📝 Walkthrough

Walkthrough

This PR updates clerk whoami to display linked application details and adds a --json flag. It introduces WhoamiOptions and profileLabel, wires --json into the CLI, resolves a local profile best-effort, emits a structured JSON payload when requested or in agent mode, and otherwise prints the email plus a conditional "Linked to …" line to stderr. Tests and documentation were expanded to cover human and JSON modes, normalization rules, and stdout/stderr pipe contract.
