#340 fix(dev): clean startup, worklog pipeline wiring, and a11y capture gate

[Anonymous]

Originally created by: adityaharishch

Summary

• dev-start.sh: clear ui/.next cache on each run so stale module references (e.g. deleted instrumentation.ts) don't break beforeDevCommand; add ui/node_modules preflight so the error surfaces clearly; kill stale Meridian Dev.app process before relaunching
• install.sh: add npm install in ui/ during dev-path setup so ui/node_modules is present when npm run tauri dev runs beforeDevCommand
• src/main.rs: wire worklog_pipeline::run_loop (calls /worklog_hour hourly) instead of the decommissioned pm_worklog::run_loop (was calling /synthesise_worklog → 404)
• tray/src-tauri/src/commands/health.rs: gate the a11y-helper trust check behind #[cfg(not(feature = "capture"))] — in-process capture builds don't use the a11y-helper binary, so the banner must never fire
• services/agents/observability.py: add instrument_agno() and current_traceparent() for W3C traceparent propagation from agno-based pipelines

Test plan

• [ ] Fresh clone → bash install.sh (dev path) → bash dev-start.sh — no next: No such file or directory error
• [ ] Re-run bash dev-start.sh — ui/.next is cleared, no stale module error
• [ ] Tauri dev build with --features capture — health check returns no a11y_helper_trusted field, a11y banner absent
• [ ] MLX server logs — no more POST /synthesise_worklog 404; /worklog_hour called on the hour instead

Fixed the current_traceparent finding — now uses TraceContextTextMapPropagator().inject(carrier) instead of hand-rolling the W3C format string, matching the extraction pattern and handling tracestate correctly.
