ObjectPoolLinter 1.0.0

First published release: the ObjectPoolLinter package on nuget.org, plus the Unity
.unitypackage and UPM .tgz attached to the GitHub release. The 0.x versions below were never
published.

Changed

• The OPL001 message names the allocation consistently and puts it first:
  'new List<int>' allocates inside the frequently-called method 'Update'. Allocations are named
  from the resolved type rather than the source text, so new System.Collections.Generic.List<int>(),
  new List<int>() and new() all read new List<int>, and arrays read as their type
  (new int[]) instead of echoing the size (int[10]). Instantiate calls read
  'Instantiate' allocates inside ... rather than 'Instantiate' is allocated inside ....
  Anything that parses the message text needs the new wording; build/verify-sample.ps1 is updated.
• The message format arguments are in reading order: {0} is the allocation, {1} the method.
  Closes A6.
• OPL001 moved from AnalyzerReleases.Unshipped.md to a Release 1.0.0 section in
  AnalyzerReleases.Shipped.md.

Build

• The release workflow publishes to nuget.org with Trusted Publishing instead of the static
  NUGET_API_KEY secret. NuGet/login@v1 exchanges the job's GitHub OIDC token for a one-hour API
  key, so no long-lived key is stored. The workflow now requests id-token: write and reads the
  nuget.org profile name from the NUGET_USER secret.
