vim.g.blamer_template no longer works #66

I tried customizing the blame format, but vim.g.blamer_template is ignored — the plugin always shows the default output regardless of the value.

Environment:

Neovim: v0.12.0-dev

blamer.nvim: latest (as of today)

Steps to reproduce:

vim.g.blamer_enabled = 1
vim.g.blamer_template = '<committer> • <summary>'

Expected behavior:
Blame info should display using the custom template.

Actual behavior:
Only the default format is shown, template changes have no effect.
