Adding tasks with prefix of length 8, 9, and other random lengths causes a panic

[LJNIC]

Describe the bug
Adding a task with a prefix of 8 or 9 causes a panic. From further testing some longer lengths like 49 also cause a panic.

Setup
Please complete the following information along with version numbers, if applicable.

• omm 0.5.0
• Fedora 40
• same behaviour with zsh, fish, and bash
• kitty
• no multiplexer
• en_US.UTF-8

To Reproduce
Steps to reproduce the behavior:

1. Add a task with length 9.
2. Panic

Expected behavior
No panic.

Screenshots
This is from length 49 but it's always a similar error, just a different index.

Caught panic:

runtime error: index out of range [-59]

[dhth]

Hi. Thanks for the report.
Could you check if the change pushed on this branch fixes things? Thanks.

[dhth]

Forgot to mention, asking you to verify this since I can't seem to reproduce this on my machine (mac arm64).

On native mac:

In a docker container running arm64 linux:

In a docker container running amd64 linux:

[LJNIC]

Yep, works on that branch!
