feat: add issue view with body cleaning and truncation (task 0003)

Add `issue view <n>` as the first detail command, introducing the
content-cleaning and truncation machinery (src/body.ts) that later issue
and PR slices reuse.

- Default output: number, title, state, author, created, body (truncated
  at 500), plus comment_count; --comments expands every comment (bodies
  truncated at 800); --full suppresses all truncation.
- cleanBody runs only when a body exceeds its limit: normalizes Gitea
  issue/PR URLs on the detected host to Issue#N/PR#N, strips image embeds
  and long URLs, and collapses quoted blocks.
- Type guard: a PR number fails with VALIDATION_ERROR and a `pr view <n>`
  hint, detected via the fetched object's pull_request field.
- renderDetail joins the detail entity, optional sub-blocks, and help.

+## Implementation Notes
+
+The cleaning/truncation machinery lives in a new `src/body.ts` (`cleanBody`, `truncateBody`, and the `BODY_TRUNCATE_LIMIT`/`COMMENT_TRUNCATE_LIMIT` constants) so the later issue/PR slices can reuse it.
+`renderDetail` was added to `src/render.ts` alongside `renderList`, sharing a private `encodeRows` helper for the `(none)` empty-block form.
+
+`comment_count` is emitted only in the default view; when `--comments` is passed, the full `comments` block replaces it rather than sitting alongside a redundant scalar.
+This matches gh-axi's documented behaviour ("with `--comments`, the comments block is appended") — the spec lists `comment_count` as a default field but does not require it to persist under `--comments`.
+When there are no comments, `comment_count` renders as the bare number `0` (no `use --comments` hint, since there is nothing to expand).
+
+The `--full` next-step suggestion fires whenever the rendered body differs from the raw body — i.e. it was cleaned-under-limit *or* truncated — read directly off the rendered output rather than recomputing the over-limit threshold, so the suggestion can never drift from `truncateBody`'s own decision.
+
+The default detail fields (`number`, `title`, `state`, `author`, `created`) reuse the shared `FieldDef`/`extractRow` extraction from the list path; only `body` and `comment_count` are handled bespokely.
+As a consequence the displayed `number` comes straight from the fetched issue rather than falling back to the requested number, which is safe because the get-issue endpoint always returns it.

+The `origin` remote is a self-hosted **Gitea** instance (`git.alexion.dev`), not GitHub.
+The `gh` CLI does not work here — open pull requests with `tea pr create --login axi --base main --head <branch>`, and list them with `tea pr`.
+
+Task branches are merged into `main` on the remote, so the local `main` goes stale.
+Always `git fetch origin` and cut a task branch from `origin/main`, not from whatever local `main` happens to point at.
