fix(ci): remove prerelease semver bootstrap dependency

[luoye520ww]

Summary

Restore the Daily Dev Prerelease prepare job, which currently fails before any platform build starts because it requires semver before dependencies are installed.

Recent runs 33187362921, 33223408802, and 33248594729 all stop in Compute dev version with MODULE_NOT_FOUND: semver.

Changes

• remove the prepare job's undeclared runtime dependency on semver
• validate the generated version against the exact canonical 0.0.0-dev-YYYYMMDD-HHMM value derived from dev_version
• preserve the existing date-format validation and all output values

Tests

• dependency-free reproduction before the fix: node -e 'require("semver")' exits 1 with MODULE_NOT_FOUND
• canonical valid pair accepted with exit 0
• mismatched app version rejected with exit 1
• malformed dev version rejected with exit 1
• workflow YAML parse passed
• node scripts/check-extension-release-gate-workflows.mjs passed
• git diff --check passed

Blocking deployment issue: scheduled workflows are loaded from the repository default branch, which is currently master, while this PR targets develop. Run 33270203067 (and the preceding scheduled runs) has headBranch=master and still executes the old inline require("semver") step even though actions/checkout later checks out develop. The replacement logic in this PR is correct, but merging it only to develop will not restore the scheduled job. Please pair this with the repository-approved master/default-branch backport or sync path, then verify a scheduled run reaches the platform jobs. Local workflow contract/YAML/diff checks pass.

Addressed the default-branch deployment-path blocker with companion backport #1246 targeting \master. The backport is a single commit directly atop current master and contains only the workflow bootstrap fix; #1242 remains the develop-side change. Local workflow contract/YAML/version-matrix/diff checks pass. After #1246 merges, I will verify that the next scheduled run reaches the platform jobs.

The deployment blocker from my earlier review is now resolved: companion PR #1246 has merged the identical workflow fix into the default branch master (merge commit 8981734). This PR should also merge into develop so future branch synchronization cannot restore the dependency. The replacement validation is correct and all PR checks pass.
