"""
push.py — local store -> Gitea.

Pushing is additive. The local file is never deleted and never moves: it gains
`gitea:`, `url:` and `synced:`, and `origin:` flips from `local` to `gitea`.
One issue, two places it is visible — not two kinds of file. A local-only issue
is a finished state, not a step on the way to a tracker.

    push.py                       every local-only issue, dependencies first
    push.py wire-sqlc-appclick    one issue
    push.py --update <id …>       PATCH issues that are already in Gitea
    push.py --dry-run             validate only, no network

Before anything is sent, each issue is validated against the canonical format
by the domain layer (exactly one type/*, English title with no type prefix,
`## Summary` / `## Spec` / `## Acceptance criteria` present). `--force` posts
anyway; say why when you use it.

Dependencies are pushed in topological order so a parent is created after the
issues it depends on. A dependency that is still local-only is reported, not
silently dropped — the body's `## Depends on` prose is sent verbatim either
way, so nothing is lost, but the `#N` cross-links will be missing.

Missing labels are created with the canonical color and, for type/* and
severity/*, `exclusive: true` — `tea labels create` cannot set that field.

`branch:` carries Gitea's `ref`, the branch the work lives on. An empty one is
filled with the current git branch and written back to the file; one that is
already set is never touched. Detached HEAD, or no repo at all: no `ref` is
sent and a warning says so.
