fix(search): shorten direct retrieval and simplify result states

[icecrasher321]

Summary

• Limit direct Search vector retrieval to 3 seconds; keep the 8-second default for Assistant and existing callers. Keyword and tag budgets stay unchanged.
• Remove partial-result notices and retry controls from returned Search results. Empty searches show “Search found no results.”
• Keep timeout coverage and the effective vector budget in server diagnostics.

Type of Change

• Bug fix

Testing

• 123 targeted unit tests passed, covering route budget selection, retrieval budgets, Search states, and KB block behavior.
• 15 PostgreSQL integration cases passed, including a delayed vector query timing out in direct Search while completing through Assistant. One optional Go-server case skipped.
• Typecheck, lint, all 46 CI audits, block-registry and docs-manifest checks passed.
• Verified populated and empty Search states in the browser.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

The PR appears safe to merge, with the shortened dashboard vector budget correctly isolated from existing Assistant and workflow behavior.

Summary

• Propagates the optional vector budget through the application and retrieval layers.
• Records the effective vector budget in search diagnostics.
• Simplifies dashboard result states by removing partial-result messaging and retry controls.
• Adds unit and PostgreSQL integration coverage for budget selection, timeout behavior, diagnostics, and UI states.
