fix(ci): emit TypeScript declarations in tag npm publish workflow

[dearlordylord]

Follow-up to #10768.

#10768 fixed the manual npm publish workflow (.github/workflows/publish-npm.yml) by running rush validate before safe-publish.js, but there is a second npm publication path in .github/workflows/main.yml: the tag-release publish-npm job.

That job still runs:

- name: Building...
  run: node common/scripts/install-run-rush.js build
- name: Publish to npm
  run: node common/scripts/safe-publish.js

So tag releases can still publish packages after rush build only. rush build emits lib/; declarations are emitted by rush validate. This appears to be why 0.7.423 was published without declarations again.

Evidence

Previous report and fix:

• @hcengineering/* packages at 0.7.413 published without TypeScript declarations #10767 reported 0.7.413 packages advertising types/index.d.ts while omitting types/.
• fix(ci): emit TypeScript declarations before npm publish #10768 fixed that for .github/workflows/publish-npm.yml.

Current regression:

pnpm view @hcengineering/core@0.7.423 types
# types/index.d.ts

tmp=$(mktemp -d)
url=$(pnpm view @hcengineering/core@0.7.423 dist.tarball)
curl -fsSL "$url" -o "$tmp/core.tgz"
tar -tzf "$tmp/core.tgz" | grep '^package/types/'
# no output

@hcengineering/core@0.7.423 and @hcengineering/client@0.7.423 npm metadata point at git head a00c01352d8ca78cf4a1367d57d136c7908d2dcb.

The tag workflow run for v0.7.423 is:

https://github.com/hcengineering/platform/actions/runs/25616518363

That publish path comes from .github/workflows/main.yml, not the workflow fixed in #10768.

Local before/after

On tag v0.7.423, after clearing generated output for @hcengineering/core:

Step	lib/index.js packed	types/index.d.ts packed	types/ entries
rush build --to @hcengineering/core	yes	no	0
rush validate --to @hcengineering/core after build	yes	yes	94

So adding rush validate before publish fixes the packed artifact contents.

Change

Add the same declaration-emission step to .github/workflows/main.yml's publish-npm job that #10768 added to .github/workflows/publish-npm.yml.
