Implements the turndown Agent Note from the NIH dependency audit (full variant, not the minimal entities-only fallback): dsh-tool-web's fetch rendering now converts HTML through turndown + @joplin/turndown-plugin-gfm (atx headings, fenced code, dash bullets, GFM tables/strikethrough) over the real domino DOM, with script/style/noscript removed wholesale. The hand-rolled ~86-line regex converter html.ts and its entity tables are deleted; renderBody wraps the conversion in try/catch falling back to the raw HTML body, because turndown's recursive DOM walk overflows with a RangeError on pathological nesting (measured: 4k levels on the main thread, 8k in a worker) where the regex version could never throw. Closure weight, measured: tool-web IS in the single-exe runtime closure, and the exe asset globs would pack ~7.9 MB of the three new packages — but ~6 MB of that is domino's test corpus, with runtime lib/ at ~550 KB against a ~174 MB artifact (<0.5% either way), so the swap wins. Per testing policy the previously-missing keyless web_fetch snapshot ships in the same change: the acp-agent `web-fetch` scenario boots a new web.cordis.yml overlay (web seam + real dsh-web-fetch-local provider + tool-web fetch-only + a loopback HTTP fixture server on a fixed port serving deterministic HTML with entities, a GFM table, and nesting), so recording and keyless replay both drive the real HTTP fetch and real conversion end to end; the scenario pins the new `web` header class. The Agent Note moves proposed -> implemented and is rewritten per the lifecycle contract (Decision/Consequences/Testing, closure verdict and alternatives recorded); tool-web and acp-agent READMEs updated in both languages and pairs re-recorded.

The interface lives at web/web/. Unlike bash/fs, the seam spans two capabilities (search and fetch) with potentially multiple providers each: ctx.web is one web-access middle layer with one provider-selection policy, one abort/error vocabulary, and one product-facing "how this harness reaches the web" config surface. Providers register capabilities, not tools; tool-web is the only owner of model-facing names, schemas, prompt guidance, and presentation. A search provider swap does not change how the model asks for a query, and a fetch implementation swap does not change how the model asks for a URL.
See the web capability seam Agent Note for the design rationale, including why search and fetch are deliberately one seam and why web_fetch's SSRF protection is deferred.
