chore: harden vite externals to prevent CJS-in-ESM bundling (#4946)

* chore: harden vite externals to prevent CJS-in-ESM bundling

Apply the same external shape used by eds-tokens-sync (#4883) to the
remaining vite configs so a transitive dep importing node: built-ins
(or bare-name built-ins) can't be silently bundled into ESM output:

- eds-tokens-build: replace explicit node:* with /^node:/ regex; add
  bare-name fs, os, crypto, process
- eds-tokens/vite.generate-variables: add /^node:/ regex and process
- eds-color-palette-generator: replace explicit node:* with /^node:/
  regex; add bare-name fs, path, os, crypto, process

Builds verified: dist/ output is byte-identical against pre-change
baseline for all three packages.

Closes #4886

* chore: align eds-tokens-sync externals with the four-config canonical shape

Add 'crypto' and 'process' to the bare-name list so all four vite configs
share the same Node built-in external shape, addressing the consistency
nit raised in PR #4946 review.

Dist output is byte-identical to pre-change baseline.
