fix(update): only require fleet verification for gateway runtimes

[wooyongbin3-cpu]

Summary

This PR fixes #97332 by only requiring fleet verification for gateway runtimes, not dashboard/serve runtimes.

Problem

The updater was treating any runtime (dashboard, serve) as evidence that gateway fleet verification was needed. This caused hermes update to exit 1 even when only a dashboard was running and the update succeeded.

Solution

Filter pre_update_plan.runtimes to only count gateway runtimes as evidence requiring fleet verification:

has_gateway = any(
    getattr(r, 'kind', '') == 'gateway'
    for r in pre_update_plan.runtimes
)
if has_gateway:
    return True

Dashboard/serve-only plans no longer trigger the gateway fleet check.

Changes

• Modified hermes_cli/update_cmd.py: Added gateway-specific filtering in _fleet_probe_expected_runtimes

Duplicate of #97350: both make fleet verification expect rows only for gateway-kind plan records. #97350 is the earlier, test-covered implementation.

Same fix landed in #103478 (f58fcc8) via the earlier #97350 by @liuhao1024 (cherry-picked with credit). Thanks for the report.
