Add pulumi, d2, jj, and nx tool definitions

[EliSchleifer]

Summary

Adds four tool definitions that trunk-cloud currently carries as custom downloads +
tools.definitions blocks in its own .trunk/trunk.yaml, because none of them exist in this
plugin source. Upstreaming them removes ~60 lines of local config per consuming repo.

• tools/pulumi — Pulumi CLI (IaC). Unix tarballs hold pulumi/<binary> (one level to
  strip); the Windows zip nests one level deeper (pulumi/bin/pulumi.exe), so it gets its own
  download entry with strip_components: 2. Stripping to the tool root keeps the CLI's bundled
  pulumi-language-* / pulumi-resource-* plugins adjacent to the binary, which it requires.
• tools/d2 — D2 declarative diagram language. Every platform ships a
  .tar.gz (Windows included; the .msi is skipped). Follows the gh pattern — strip_components: 1
  plus ${tool}/bin on PATH — rather than stripping two levels, so the bundled LICENSE/man
  files survive.
• tools/jj — Jujutsu VCS. Note the asset naming is
  ${cpu}-${os} (a target triple), the reverse of most tools here, and there is no
  strip_components: the archives hold jj at their root alongside README/LICENSE.
  Windows ships .zip instead of .tar.gz, so it needs a separate entry.
• tools/nx — Nx monorepo task runner, a plain runtime: node package.

Note on the jj health check

jj --version prints jj 0.45.1-<commit sha>. ${semver} parses the sha as a prerelease suffix,
so the health check fails with Expected '0.45.1' but got '0.45.1-7c41cdeb...'. The definition
uses an explicit jj (\d+\.\d+\.\d+) to capture only the x.y.z prefix; there's a comment in the
file so a future editor doesn't "simplify" it back to ${semver}.

Test plan

Each tool uses a health_checks entry + toolInstallTest, per the guidance in
repo-tools/tool-test-helper/tool_sample.test.ts.

• npm test tools/pulumi tools/d2 tools/jj tools/nx — 4 suites passed, 4 tests passed
• trunk tools install verified against each known_good_version (pulumi 3.210.0, d2 0.7.1,
  jj 0.45.1, nx 22.5.3) in a sandbox repo using plugins: sources: local:
• Verified again against each tool's latest release resolved by trunk tools enable
  (d2 0.8.2, nx 23.2.0), so the definitions aren't pinned-version-specific
• Ran each shim: d2 --version, jj --version, nx --version, pulumi version
• trunk fmt + trunk check clean on the new files
• Windows and macOS paths are unverified — no runner available locally. All four URL patterns
  and archive layouts were confirmed against the published release assets, and the Windows
  differences (pulumi's deeper zip nesting, jj's .zip extension) are handled explicitly.
