eds wf job logs: always prints raw JSON, ignoring the table/--json FormatAuto convention

[rawen554]

Context

Every other subcommand in cmd/job.go (newJobShowCmd, newJobListCmd,
etc.) checks ctx.Printer.Format == output.FormatJSON and falls back to a
table/KeyValue rendering on a TTY, per the convention documented in
CLAUDE.md ("every subcommand that returns structured data should support
both table... and --json output via ctx.Printer").

newJobLogsCmd (added in PR #1) calls ctx.Printer.PrintJSON(resp)
unconditionally, so eds wf job logs <id> always dumps raw JSON even when
run interactively without --json.

Discussion

PR #1's author argues this command is agent-only and a human table view
isn't needed. That may be a reasonable call, but it should be a deliberate,
documented exception rather than an accidental one-off — right now it's
just inconsistent with every sibling command in the same file, with no
comment or doc explaining why.

Ask

Either:

• make logs follow the same FormatAuto convention as its siblings
  (plain-text log lines on TTY, JSON via --json/pipe), or
• if agent-only JSON output is intentional, document that explicitly in
  code (comment) and in skill/SKILL.md, and consider whether other
  Workflow Studio commands should follow the same rule for consistency.
