Performance Regression: Slow startup in repos with many annotated tags

[willbush]

Describe the bug

The other day I updated to v0.53.0 and noticed a huge delay on statup on lazygit in a private repo I work in.

lazygit -d gave a clue it was related to tags:

{"level":"info","msg":"refreshed tags in 7.866606855s","time":"2025-07-25T22:16:58-05:00"}

Indeed, I cloned the repo without tags and had no issue. We have a large number of git tags ~8k at the moment for reasons..

I tried to reproduce the issue by creating 8k tags on 1 commit, but ran into a panic instead: #4765
I then tried to break up 8k tags across many commits, but could not replicate any perf issues.
However, I realized that if the git tags are annotated (as most of ours are) then I can repro the perf issue in a new git repository.

I used git bisect to narrow it down to this commit (see Additional context section for steps I did):

To Reproduce

1. create test git repo: mkdir tester && cd tester && git init
2. create a random message for git annotated tag: MSG=$(head -c 10000 /dev/urandom | base64). Note 10k bytes is just to make the delay more noticeable. It can by half of this and still noticeable.
3. generate 5k commits each with a annotated git tag:

for i in $(seq 1 5000); do git commit --allow-empty -m "Commit for tag #$i"; git tag -a "tag-$i" -m "$MSG"; done

4. lazygit or lazygit --debug for debug mode with logging.
5. Spam right arrow key to cycle panes. If you're fast enough, you can initially make it to the next pane before it freezes. Keep pressing right arrow to see when it is no longer frozen.

Here's my development.log for tester repo (refreshed tags in 4.411122778s is about half of the delay compared to private repo with ~8k annotated tags.) I'm not sure if delay depends more on the number of annotated tags or the length of the tag messages:

Expected behavior

Should not freeze on startup.

Thanks for the bisecting, makes it very easy to see what needs to be done. I'll revert that commit and find another way to achieve the same; shouldn't be too hard. I hope to get this done some time next week, in time for the next release next Saturday.

@willbush This should be fixed in #4777, can you please test and/or review?
