fix(ci): repair the publish chain so the workflow can actually run

[beyondnetPeru]

Same workflow defect as beyondnetcode/Shell.Aop#8 (already merged and green), plus two packaging bugs unique to this repo that made dotnet pack fail outright.

Root cause 1 — the workflow was never valid

on: declared tags: as a top-level key, which is not a GitHub Actions event:

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main, develop]
  tags:          # <- not a valid event
    - 'v*'

GitHub rejects the whole file. Every run in this repo's history failed in 0 seconds with "This run likely failed because of a workflow file issue" — the 58 tests in this repo have never run on any commit.

Root cause 2 — pack failed before producing anything

Two bugs in the .csproj files, both invisible until the workflow could actually run:

1. NU5019 — file not found. Every project referenced ../../LICENSE and ../../README.md (../../../ in one case), paths that assume a src/<project>/ layout. The projects live at the repo root, so those paths resolve outside the repository. Corrected to ../.

2. NU5030 — license file not in the package. <PackagePath>LICENSE</PackagePath> has no file extension, so NuGet treats it as a directory: the file landed at LICENSE/LICENSE while <PackageLicenseFile>LICENSE</PackageLicenseFile> looked for it at the root. Corrected to <PackagePath>/</PackagePath>, which places the file at the package root under its own name. README.md was unaffected because its extension made NuGet read it as a file path.

Worth noting: the same LICENSE/LICENSE misplacement exists in Shell.Factory and is fixed in its parallel PR. Shell.Aop and Shell.Bootstrapper are unaffected — they use PackageLicenseExpression instead of a packed file.

Workflow fixes

• tags: ['v*'] moved under push:
• version job: dropped github.event_name == 'tag' — tag pushes arrive as push
• pack matrix points at the real project locations (repo root, not src/)
• -p:PackageVersion= replaces --version:, which is not a dotnet pack option
• --no-build dropped; the job runs on a fresh runner with nothing pre-built
• matrix values are folder names — upload-artifact rejects names containing /
• release now depends on publish
• workflow renamed CI / CD → CI; README badge switched to the file-based URL

Verification

Locally on .NET 10.0.201 (matching global.json):

dotnet build BeyondNet.Ddd.slnx -c Release  → 0 errors (15 warnings)
dotnet test  BeyondNet.Ddd.slnx -c Release  → 58/58 passed
dotnet pack  <each of the 3 matrix projects> -p:PackageVersion=9.9.9-test

All three packages produced, each with lib/net10.0/, and LICENSE + README.md at the package root — verified with unzip -l.

Before releasing

NUGET_API_KEY must exist in the nuget-release environment, or publish fails at the last step.
