Give tool_prefix back the documentation it already had

[sanil-23]

Summary

main has been red since #74: the Rust lane's clippy step and the Docs lane both fail on missing documentation for a method at EpisodeHost::tool_prefix. Every branch cut from main inherits it — #76 is failing on this and nothing else.

Nothing was ever missing. tool_prefix's doc block is intact; it sits above persona, fused to persona's own opening line with no blank line between them:

/// ... vocabulary, so a host that prefixes says so in its own prompt.
/// The seat's own standing prompt, for the turns that are not its first.
///
/// A seat's session is cleared and reseeded ...
fn persona(&self, seat: &str) -> Option<String> { ... }

fn tool_prefix(&self) -> String {   // ← bare
    String::new()
}

A merge slip rather than a gap: the prose describing the prefix still reads correctly, it is simply attached to the wrong method. Moving tool_prefix back under its own doc fixes both lanes and changes no behaviour.

Related issue

None. Found while investigating CI on #76, which is blocked by this and by nothing of its own.

API or behavior changes

None. One method moved a few lines up, under the documentation written for it. No signature, no default, no call site.

Validation

• cargo fmt --all -- --check — exit 0
• cargo clippy --all-targets --all-features -- -D warnings — exit 0 (this is the lane that has been failing)
• cargo build --all-targets --all-features — exit 0
• cargo test --all-features — exit 0, 36 targets, unchanged
• cargo doc --no-deps --all-features — exit 0 (the other failing lane)

Tests

None added. The regression is a lint, and the two lints that caught it are the test — both were failing on main and both pass here.

Documentation

This is the documentation fix. No prose was written or changed; the existing block is simply reunited with the method it describes.

Agent review details

critique

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: The change only relocates the default `tool_prefix` implementation without changing its behavior or the public contract. It is safe to merge. _The code index is behind this pull request (indexed at `cd23c7fed5b0`), so retrieved context may be out of date._ _5 memory call(s) failed (model: cortex: v1/recall: timed out after 10s), so this review saw part of what the engine holds._

security

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: The change only relocates the default `tool_prefix` implementation within the trait implementation; behavior is unchanged and the change is safe to merge. _The code index is behind this pull request (indexed at `cd23c7fed5b0`), so retrieved context may be out of date._ _5 memory call(s) failed (model: cortex: v1/recall: timed out after 10s), so this review saw part of what the engine holds._

tests

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: Reorders the `tool_prefix` method in `EpisodeHost` trait to appear earlier and adds a default implementation returning `String::new()`. This is a purely additive change — existing implementors already provide their own `tool_prefix` and are unaffected, and new implementors get a safe default. No behaviour regresses and no test is needed. _The code index is behind this pull request (indexed at `cd23c7fed5b0`), so retrieved context may be out of date._ _5 memory call(s) failed (model: cortex: v1/recall: timed out after 10s), so this review saw part of what the engine holds._
