[Bug] on-run-end runs before on-run-start on actions other than build

[frankivo]

Is this a new bug in dbt-core?

• I believe this is a new bug in dbt-core
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

I have a project with some hooks: both on-run-start and on on-run-end.
Whenever there are models to be run, the order is fine.

However when there no models to be run, the order may be incorrect.
I see the on-run-end hooks running before (or paralel) with on-run-start hooks.

Expected Behavior

I would expect the on-run-end to start after on-run-start is done executing.

Steps To Reproduce

hook config:

on-run-start:
  - "{{ log('Run type: ' + flags.WHICH, info=True) }}"
  - "{{ log('Pre-hook: on-run-start', info=True) }}"

on-run-end:
  - "{{ log('Post-hook: on-run-end', info=True) }}"

• execute dbt build and check logs (should be correct)
• execute dbt compile and check logs (may be correct)

tested against dbt-core 1.8.6 and dbt-core 1.9.2

Relevant log output

12:14:47  Running with dbt=1.9.2

12:14:48  Post-hook: on-run-end
12:14:48  Run type: compile
12:14:48  Pre-hook: on-run-start

Environment

- Python: 3.12.8
- dbt: 1.8.6 / 1.9.2

Which database adapter are you using with dbt?

other (mention it in "Additional Context")

Additional Context

occurs with dbt-databricks and dbt-duckdb. assuming it is not relevant for this issue.
