refactor: convert remaining Tier 1 commands to return-based output

[BYK]

Summary

Convert 5 remaining Tier 1 commands to the return-based CommandOutput<T> pattern introduced in #380.

Each command now returns { data, hint?, footer? } and declares an OutputConfig with json: true and a human formatter — the framework handles JSON serialization and human-readable rendering.

Commands converted

Command	Human formatter	Return shape
event/view	formatEventView()	{ data: { event, trace, spanTreeLines }, hint }
issue/view	formatIssueView()	{ data: { issue, event, trace, spanTreeLines }, footer }
issue/plan	formatPlanOutput()	{ data: { run_id, status, solution } }
project/create	formatProjectCreated()	{ data: ProjectCreatedResult }
trace/view	formatTraceView()	{ data: { summary, spans, spanTreeLines }, footer }

Infrastructure changes

• Added footer?: string to CommandOutput<T> and RenderContext
• renderCommandOutput() now renders footer via writeFooter()
• handleReturnValue in command.ts passes value.footer through

What was removed

• writeHumanOutput() from trace/view (replaced by formatTraceView)
• outputSolution() from issue/plan (replaced by formatPlanOutput + buildPlanData)
• Manual writeJson/writeFooter/stdout.write calls from all 5 commands
• Writer type imports (no longer needed)

Test updates

• test/commands/trace/view.func.test.ts: writeHumanOutput tests replaced with formatTraceView pure function tests
• test/commands/project/create.test.ts: parsed.slug → parsed.project.slug (JSON shape now uses full ProjectCreatedResult)

Net: -33 lines (188 insertions, 221 deletions)

Part of the output convergence plan: #373 → #376 → #380 → this PR
