jakevin 977105b0f6 feat(hackernews): add read <id> and surface item id on every listing (#1288)
* feat(hackernews): add `read <id>` and surface item id on every listing

Two related agent-flow gaps in the HN adapters:

1. `top`/`best`/`ask`/`new`/`show`/`jobs`/`search` all carry the HN item
   id internally (firebase items are fetched by id; algolia hits include
   `objectID`) but drop it before output. Without an id column the agent
   can see the title but has no handle to follow up with.

2. There was no way to read a story's discussion. The whole reason an
   agent looks at HN is the comments — and that capability was missing.

This PR adds:

- `id` column on every listing adapter (firebase items: numeric id;
  algolia search hits: `objectID` string). Existing column order is
  preserved otherwise.
- `hackernews read <id>` — public/non-browser adapter that fetches the
  story plus a tree of top-level comments + inline replies via
  `https://hacker-news.firebaseio.com/v0/item/<id>.json`. Mirrors the
  `reddit read` shape (`type/author/score/text`) so agents can use both
  with one mental model. HTML-only fields (comment text) are converted
  to plain text with anchor URLs preserved.
- Column-contract tests covering all listings + the new read adapter.
- Doc entry under `docs/adapters/browser/hackernews.md`.

Tested locally via `~/.opencli/clis/hackernews/` overrides:
  opencli hackernews top --limit 3            # id present
  opencli hackernews search rust --limit 2    # id (objectID) present
  opencli hackernews read 47999636 --limit 5  # threaded output

* fix(hackernews): typed fail-fast for read
