P1-T5: Fix missed --broker-spawn references in troubleshooting.md "MCP tools are green" section

[SoundBlaster]

Description

Complete FLOW delivery for P1-T5 and archive the task artifacts.

Task result: this was a verified no-op against current main content. The originally reported stale --broker-spawn references in docs/troubleshooting.md were already corrected upstream (--broker --web-ui), so this PR records validated completion with full quality gates, review, and archive bookkeeping updates.

Key updates:

• Added/archived P1-T5 PRD + validation report under SPECS/ARCHIVE/P1-T5_Fix_missed_broker_spawn_references_in_troubleshooting/
• Updated SPECS/Workplan.md to mark P1-T5 completed (2026-03-04)
• Updated SPECS/INPROGRESS/next.md to idle state with suggested next task (P1-T6)
• Updated SPECS/ARCHIVE/INDEX.md with archived-task and review-log entries
• Archived review report to SPECS/ARCHIVE/_Historical/REVIEW_p1_t5_troubleshooting_broker.md

Validation artifact:

• SPECS/ARCHIVE/P1-T5_Fix_missed_broker_spawn_references_in_troubleshooting/P1-T5_Validation_Report.md
