Expand audit selector rules to cover gaps surfaced by 14-day PR replay

Replayed the 161 PRs merged to main between 2026-05-23 and 2026-06-06
through the audit selector. v1 (the prior file) resolved 89/161 PRs to
'selective' and dropped 26/161 to 'fallback_unmatched' (any unmatched
file forces RunAll). After this change all 161 PRs classify cleanly:
18 skip, 32 trigger_all, 111 selective, 0 fallback.

Additions:

* ignorePaths — files that never need a test gate but were forcing
  fallback today: .vscode/**, .mcp.json, localhive.{sh,ps1},
  .github/{extensions,policies,aw}/**, .agents/** (CLI agent skill
  content, consumed only by humans/agents), eng/scripts/debug-*.{sh,ps1}
  (developer-loop helpers), eng/scripts/cli-starter-validation*.ps1
  (consumed by the always-on cli_starter_validation_windows job, which
  isn't conditional-selector-gated).

* sourceToTestMappings — scripts and infra files that have a specific
  test home but weren't wired up: eng/Publishing.props,
  eng/Signing.props, eng/scripts/{pack,stage,verify,validate}-cli-*
  and tools/TypeScriptApiCompat/** all map to Infrastructure.Tests
  (its Pipelines/ and PowerShellScripts/ folders test these scripts).
  eng/scripts/get-aspire-cli{,-pr}.{sh,ps1}, eng/scripts/verify-cli-archive.ps1,
  eng/homebrew/** and eng/winget/** map to Aspire.Acquisition.Tests
  (the script-suite that exercises them). eng/scripts/update-aspire-
  skills-bundle.ps1 + verify-aspire-skills-bundle.ps1 map to
  Aspire.Cli.Tests (AspireSkillsBundleTests). Two self-mappings for
  tests directories without a 'tests/Aspire.*.Tests/**' shape:
  tests/Infrastructure.Tests/** and
  tests/Aspire.Hosting.CodeGeneration.TypeScript.JsTests/**.

* polyglot.triggerPaths — expanded beyond the workflow file itself to
  cover the polyglot fixture tree (tests/PolyglotAppHosts/**) and the
  per-language Aspire.Hosting.{JavaScript,TypeScript,Python,Go,Java,Rust}
  + CodeGeneration* projects. Without these, polyglot-impacting PRs
  (#17545, #17499, #17419, #17400, #17382) all fell into RunAll.

Local verification: 251 TestSelector/PowerShellScripts/ConditionalSelection
tests still pass. The CI-trigger-pattern coverage test (which loads this
file from disk) is unchanged because we only added to ignorePaths and
sourceToTestMappings — no existing entries were removed or narrowed.
