feat(cli): add -f/--format to report and status built-ins

[ankitranjan7]

Rebased #306 onto current main after #341 / #361 / #363 / #364.

What

validate, verify, doctor, bare skills, and daemon status accept -f/--format and return the underlying result object. Default table text is unchanged.

webcmd validate -f json
webcmd verify -f yaml
webcmd doctor -f json
webcmd daemon status -f json
webcmd skills -f json

profile list -f already landed in #341 — this PR only adds the structured-output tests for it.

Why not merge #306 as-is

It conflicts with current src/cli.ts (validate/verify) and predates #341. GitHub’s CLEAN flag is stale; git merge-tree reports conflicts.

Supersedes

• feat: add structured output to report and status built-ins #306 (fork, same change, old base)
• feat(cli): add -f/--format to webcmd validate #322 (validate -f only)
• feat(cli): add -f/--format to webcmd daemon status #325 (daemon status -f only)
• feat(cli): add -f/--format to webcmd profile list #326 (already shipped as feat(cli): add --format to profile list and report disconnected profiles #341)

Test plan

• npm run typecheck
• npx vitest run --project unit src/cli.test.ts src/commands/daemon.test.ts src/doctor.test.ts (170 passed)
• npm run check:hosted-contract

Closing in favor of landing the original contributor PR #306. Thanks for the patience — we should have merged that branch instead of opening a replacement.
