-module only fills in ``build_provider`` so ``runtime.py``'s
-``PROVIDER_FACTORIES["get_project_issue_context"]`` resolves to a real,
-read-only Gitea client instead of :class:`UnconfiguredIssueProvider`.
-
-Design notes (documented here so a reviewer does not have to guess):
-
-* Credentials (``GITEA_TOKEN``) and the base URL are read INSIDE
-  ``build_provider``/``_resolve_target`` only — never at import time — because
-  ``build_provider`` is only ever invoked by
-  ``ProjectProviderResolver.resolve`` (see ``runtime.py``), which
-  ``server.py::dispatch`` calls strictly AFTER ``policy.decide`` returns
-  ``True``. Reading env vars at module scope would read them before the
-  policy check ever runs.
-* The provider is bound to exactly one project/repository at construction
-  time (``identity.project`` -> ``PROJECT_CONTEXT_REPO_MAP``). The
-  ``project_id`` argument received per call is only used to echo it back in
-  the response and as a defensive equality check — it is never used to pick
-  which repository to query. This means a caller can never redirect the
-  provider to an arbitrary repository by tampering with ``project_id``.
-* ``revision`` pins to the issue's own ``updated_at`` timestamp. Gitea issues
-  (unlike commits/PRs) have no natural commit SHA of their own, so the most
-  meaningful, verifiable "version marker" Gitea offers for an issue is its
-  last-modified time: given the same URL and the same ``revision`` string, a
-  reviewer can confirm whether the issue has changed since this was fetched.
-* ``related`` items are derived from BARE ``#<number>`` cross-references
-  found in the issue body — never from a ``#<number>`` that is only the
-  label text of an explicit Markdown link (``[other-repo PR #4](http://.../
-  other-repo/pulls/4)``). A real issue body regularly links to a pull
-  request or an issue in a DIFFERENT repository this way; re-guessing that
-  as "issue #4 in THIS repo" would silently point at the wrong resource
-  entirely, which is worse than omitting it — the author already gave the
-  correct URL right there, so extraction strips whole ``[label](url)``
-  spans, then any remaining bare URLs, before scanning for mentions. Titles
-  for the mentions that DO survive are NOT fetched with an extra API call
-  (kept deliberately simple and bounded) — each related item's title is a
-  generic, honest placeholder ("Referenced item #<n>"), and its ``url``
-  always resolves to a real, openable page in this same repository. This
-  is a known, documented simplification, not a bug.
-* ``acceptance_criteria`` looks for the issue's own "Acceptance Criteria"
-  Markdown heading (``#`` through ``######``, case-insensitive) and only
-  collects checklist items (``- [ ]``/``- [x]``) from inside that section,
-  up to the next heading of equal-or-shallower depth. This matters because
-  a real work-item body commonly has a SEPARATE "Definition of Done"
-  section that also uses checklist syntax — without scoping to the
-  matching heading, those unrelated items would be silently folded into
-  "acceptance criteria" and misrepresent the issue. When no such heading
-  exists at all (ad-hoc issues with no fixed template), this falls back to
-  scanning the whole body, so those issues still get a best-effort result
-  instead of an always-empty list.
-* ``truncated``/``returned``/``remaining``/``next_cursor`` describe pagination
-  over the ``related`` list only. ``description`` has its own independent,
-  generous hard safety cap (so the response stays bounded even for a
-  pathological issue body) and is never silently cut without a visible
-  notice appended.
-* The regexes that derive ``acceptance_criteria``/``related`` never scan more
-  than ``_MAX_SCAN_CHARS`` of the raw body, and always run on a copy with
-  ``http(s)://`` links stripped first — otherwise a `#42` inside a URL
-  fragment (e.g. a doc anchor) would be mis-detected as a cross-reference to
-  issue #42, and a pathologically large body would cost unbounded regex work
-  on every call regardless of the display cap on ``description``.
