Assign every new issue and pull request to the maintainer #341

New issues and pull requests in this repository have no assignee until someone sets one by hand, and I want each one assigned to me when it is made, so that it shows up in my own queue from the first minute. On 2026-11-10 I backfilled the 33 open items of ArcadeData/arcadedb-python by hand (and 30 in humemai/tiervec, 61 in total); this issue is the automation for the new ones.

Proposal: a small workflow, .github/workflows/assign-maintainer.yml, named Assign the maintainer, that runs on issues: opened and pull_request_target: opened and calls github.rest.issues.addAssignees for tae898. It uses pull_request_target so a fork's pull request still gets a token that can edit it; nothing from the pull request head is checked out or run, the job only calls the GitHub API. It uses only actions/github-script, pinned to the same full commit SHA as assign-milestone.yml, with no secrets and no checkout. An item that already has tae898 assigned is skipped, and a refused assignment (a bot, a fork pull request) logs a warning and does not fail the job. The maintainer login is the only thing to change if the maintainer ever does. Permissions are issues: write, pull-requests: write, contents: read.

I found no existing issue or pull request in this repository that does this (the closest are the milestone automation in #251 and #260, which this is modelled on).
