Change script to open usage file once and close upon completion (keep it open through execution)

[yarikoptic]

TODO: RF to keep the usage file open and close upon completion.

Also why we append to info file -- shouldn't it be just w as well?

TL;DR: full story on how ran into it:

on reproiner we run ffmpeg under `duct`. `git annex assistant` monitors / commits / pushes changes. I just got ``` yoh@typhon:/data/repronim/reprostim-reproiner$ git annex sync (merging origin/git-annex reproiner/git-annex into git-annex...) git-annex sync will change default behavior in the future to send content to repositories that have preferred content configured. If you do not want this to send any content, use --no-content (or -g) to prepare for that change. (Or you can configure annex.synccontent) commit On branch master Your branch is behind 'reproiner/master' by 1 commit, and can be fast-forwarded. (use "git pull" to update your local branch) nothing to commit, working tree clean ok pull reproiner Updating 009f7f494..c44b4e6a4 Fast-forward Videos/2024/10/2024.10.18-15.55.41.103--.mkv.duct_usage.json | 1 + 1 file changed, 1 insertion(+) create mode 100644 Videos/2024/10/2024.10.18-15.55.41.103--.mkv.duct_usage.json git-annex: The file

`Videos/2024/10/2024.10.18-15.55.41.103--.mkv.duct_usage.json` which was annexed but also got another record written to it: ```shell yoh@typhon:/data/repronim/reprostim-reproiner$ cat

git-annex.... I see this potentially happening whenever we keep reopening/appending/closing to a file instead of just keeping it open and wirting and then closing... yeap: ```shell ❯ git grep '"a"' src/con_duct/__main__.py: with open(self.log_paths.usage, "a") as resource_statistics_log: src/con_duct/__main__.py: with open(log_paths.info, "a") as system_logs: ```

oh, situation is worse as it actually currently leading to breeding those commits as we are speaking on reproiner . Will provide a PR shortly...

Summarizing the situation to ensure I understand correctly, the feature request here is that duct should be robust datalad save during a duct run that includes the duct output files.
