feat: initial text-translate v0.1.0 (text.translate@0.1.0)

Ollama-backed translation module — third real F∆I capability,
following text.extract and llm.chat. Used for the second leg of
a regulated document workflow (extract -> translate -> review
-> summarise).

Capability:
  Inputs:
    text             : text   (source text)
    target_language  : text   (e.g. "German", "French")
    source_language  : text   (optional hint; empty = auto)
    endpoint         : text   (Ollama /api/chat URL)
    model            : text
    api_key          : text   (optional)

  Outputs:
    translation      : text
    source_language  : text   (echo for audit)
    target_language  : text   (echo for audit)
    model_endpoint   : text
    model_name       : text
    model_digest     : text   (Ollama /api/show probe; empty
                                for non-Ollama or transient
                                failures)

  Permissions: net to localhost / 127.0.0.1 / api.openai.com /
               api.anthropic.com.

The translation prompt is conservative: a fixed system prompt
demands faithful translation with structure preservation and
emits no metadata, no quoting. The user prompt names the target
language and (when supplied) the source language. The LLM
client + digest-probe pattern is reused verbatim from llm-chat;
when a third module joins, the shared client moves into a small
crate.

14 host-side tests cover prompt-building, Ollama-shaped response
parsing, URL transform, digest extraction (top-level + nested),
end-to-end success, end-to-end probe-failure swallow, and
end-to-end skip-for-non-Ollama.

Wasm artifact verified to build with v1.0 fai:platform imports
baked in. Bootstrapped via 'fai new module text.translate'.

+# text-translate
+
+Provides the `text.translate` capability for F∆I Platform.
+
+## Build
+
+```bash
+cargo build --release --target wasm32-wasip2
+```
+
+## Test
+
+```bash
+cargo test                 # host-side unit + integration tests
+fai test .                 # load the wasm component in the runtime sandbox
+```
+
+## Authoring with fai-module-sdk
+
+The module body is one decorated function:
+
+```rust
+#[fai_module]
+pub fn invoke(_ctx: Context, inputs: Inputs) -> Result<Outputs, ModuleError> {
+    let message = inputs.require_text("message")?;
+    Ok(Outputs::new().with_text("reply", format!("got: {message}")))
+}
+```
+
+The macro hides the wit_bindgen call, the Guest impl, the
+Payload variant matching, and the `wit_bindgen::export!`
+invocation. See `fai-module-sdk` documentation for the full
+surface.
+
+## SDK source
+
+The Cargo.toml git-deps `fai-module-sdk` from
+`https://git.flemming.ws/fai/module-sdk.git`. If your environment requires
+authentication for that host (e.g. Forgejo with
+`REQUIRE_SIGNIN_VIEW=true`), set up `git config insteadOf` with
+your PAT, or use `cargo:net.git-fetch-with-cli=true` plus a
+credential helper.
