Finish the `issue list` flag surface left minimal by the tracer slice:
- Server-side filters `--label`, `--assignee`, `--author`, `--milestone`,
mapped to Gitea's `labels`, `assigned_by`, `created_by`, `milestones`.
- Client-side `--sort <created|updated|comments>`, always descending, over
the fully paginated set (ADR 0005); `--limit` caps the sorted result.
- `--fields` exposing body, closedAt, labels, milestone, updatedAt, url.
- `--search` refused with a VALIDATION_ERROR redirecting to `search issues`.
Exhaustive pagination lands as a shared `paginate.ts`, since ADR 0005 makes
it a policy later slices reuse; `lookup.ts` drops its hand-rolled copy of the
same loop. The helper carries the 20-page cap that copy encoded, matching the
1000-item ceiling Principle 8 sets.
Tracer bullet for gitea-axi: runnable npm package on axi-sdk-js with
gitea-js as the sole HTTP layer, ESM on Node 20+.
- issue list with --state/--limit, default fields, count line from
X-Total-Count, type=issues guard, explicit empty state, and next-step
suggestions
- repo context detection from the git origin remote (SSH/scp/HTTPS),
tea credential discovery with the three-way login-matching split, and
-R/--repo and --login overrides (flag > env > auto)
- token retrieval via tea login helper get: tea's login list JSON
carries no token (ADR 0001 amended)
- full AxiError classification table with path-based 404 split, TOON
errors on stdout, exit codes 0/1/2
- test mode (GITEA_AXI_API_URL/TOKEN/REPO) suppressing subprocesses,
fixture server, and vitest suites driving the CLI seam (50 tests)
