Introduce the first mutations, along with the shared machinery the later
issue and PR mutation slices reuse.
- `issue create` with --title/--body/--body-file/--assignee/--label/
--milestone/--fields, emitting `issue: { number, title, state, url }`
- `issue comment <n>`, echoing the created comment from the POST response
with the body cleaned and truncated at 800 chars
- body-source resolution (--body vs --body-file), label and milestone
name->ID lookup, repeatable flags, and the `joined`/`selectExtraFields`
field extractors
Label lookup pages until exhausted, since a repo with more labels than one
page would otherwise fail to resolve a valid name. The end-to-end tier seeds
a mixed-case label and milestone and passes both in a different case, so the
case-insensitive lookup is verified against live Gitea rather than only
against fixtures.
- CONVENTIONAL-COMMITS.md: vendored spec (v1.0.0); CLAUDE.md requires
agent-written commits to follow it
- tasks 0002-0020: remaining task breakdown of the gitea-axi spec
(0019 reframed around the three-tier test taxonomy: unit,
integration, end-to-end)
- spec, CONTEXT.md, and ADRs 0006/0007/0011: pending design
refinements from the planning sessions
