`git push --mirror` pushes everything under refs/* including refs/pull/*,
which GitHub rejects with "deny updating a hidden ref" — GitHub manages
its own refs/pull/N/head namespace and won't let outside pushers touch it.
Switching to `--all --prune --force` + `--tags --prune --force` scopes the
push to refs/heads/* and refs/tags/* only (same as the original lines)
while keeping --prune so branch/tag deletions still propagate.

`.mcp.json` is per-machine MCP server config (e.g. the GitHub MCP block
added during today's session). It references local env vars for auth
rather than embedding secrets, but the file itself is workstation-specific
— what servers a contributor connects depends on which MCPs they've set
up locally.

Today's cleanup surfaced 14 branches that existed on GitHub but had
been deleted on Gitea — the previous `--all --force` + `--tags --force`
pair pushes refs but never deletes missing ones, so the mirror drifted
over time.
Switching to `git push --mirror` (equivalent to --all --tags --prune
--force) makes the GitHub side a true reflection of Gitea: branch and
tag deletes propagate automatically.
