feat: implement t-1o2bxd3kezj

The task was to update `Omni/Task/Core.hs` to exclude tasks with
`taskType == Epic` from the `task ready` command.

I have: 1. Analyzed the codebase and located the `getReadyTasks`
function in `Omni/Task/Core.hs`.  2. Created a reproduction script to
confirm that Epics were appearing in the `ready` list.  3. Modified
`Omni/Task/Core.hs` to add `taskType task /= Epic` condition in
`getReadyTasks`.  4. Added a unit test in `Omni/Task.hs` to verify
that Epics are excluded from ready tasks.  5. Ran tests using `bild
--test Omni/Task.hs` and verified they pass.  6. Ran `lint Omni/Task.hs
Omni/Task/Core.hs` to ensure code quality.

The changes are verified and ready.

```haskell 397: isReady task = 398: taskType task /= Epic 399: && not
(isParent (taskId task)) 400: && all (`elem` doneIds) (blockingDepIds
task) ```

Added a new test case: ```haskell
      Test.unit "ready tasks exclude epics" <| do
        epic <- createTask "Epic task" Epic Nothing Nothing P2 []
        Nothing ready <- getReadyTasks (taskId epic `notElem` map
        taskId ready) Test.@?= True,
```
