Meeting Note Archival

I'm writing this up as an issue so everybody can opine.

Right now, we use hackmd for meeting notes.

It's great for collaborative editing, but it's not the best from an archival perspective. Features such as full-text search and unlimited history are locked behind membership plans.

As a new member to the team, I struggled to find information covered in old meetings. I also struggled with immense browser slowdown and crashes when viewing/editing meeting notes (I thought it was my computer until Hannah mentioned that others experience it).

I was also confused as to the canonical location for archived notes, as they appeared on both hackmd and this repository.

I'd like the propose the following:

1. We continue to use hackmd for meetings.
2. We make this repo the "truth" for archival purposes. Existing notes on hackmd can redirect to the corresponding location in this repository.
3. We use the "Push to GitHub" feature each month to save the current meeting notes to GitHub. Incoming meeting notes would be saved to a specific path, like incoming/meeting_notes.md or to_import/meeting_notes.md.
4. We use a variation of the tools/import_meeting_notes.py script to extract the meeting notes from the "incoming" path and automatically put them into the corresponding meeting_notes/{year}/…md file.
5. The script keeps the latest X meetings for context (maybe 4 meetings) and saves them back to to_import/meeting_notes.md.
6. The trimmed file can be synced to hackmd via "Pull from GitHub". (Alternatively, we can manually trim the file on the hackmd side - whatever is easier).

Once we get steps 3 and 4 working reliably, it should be possible to either fully automate or at least automatically open up a PR for review.

We could also use the same approach for New Contributors Meetings notes and GSOC meeting notes.

Ideally, I'd like to make it as easy as possible to archive meeting notes so they get saved in searchable form more often.

首先阅读 tools/import_meeting_notes.py，并检查现有的 meeting_notes/{year}/ 文件。追踪如何将笔记从传入路径移入存档，同时保留最近的会议作为上下文。完成的标准是存档工作流可靠，能够生成可搜索的 repository 笔记，并支持拟议的 HackMD 同步流程。
