ZacharyZhang-NY a02b555e66 docs(comments): rewrite comments across all crates to the guidelines
Sweep every first-party crate source (1956 .rs files) to the project comment
guidelines: delete redundant restatements, decorative banners, change
narration, and end-of-line comments; keep and tighten the crucial ones
(invariants, bug rationale, SAFETY blocks, ported-source attribution).

No functional code changed. Every edit is proven comment-only against the
prior tree by a comment-stripping lexer (string/char/raw-string aware) plus a
separate doctest-fence check. Where removing a comment made rustfmt or clippy
want to re-lay-out adjacent code, the minimal triggering comment is restored so
code tokens stay byte-identical.

Gates green: cargo fmt --all --check (0 diffs), cargo check and cargo clippy
--workspace --all-targets (0 warnings).

Adds scripts/check_codegen_comment_guidelines.py — the enforcement gate for
these guidelines (flags banners, end-of-line comments, change narration, and
commented-out code).

//! Single source of truth for the `kigi/mcp/*` ACP wire strings.
//!
//! These method/`_meta` keys are part of the cross-language MCP-over-ACP
//! protocol the SDK speaks (mirrors the SDK's `_mcp_wire.py` / `mcpWire.ts`).
//! Reference these constants instead of re-typing the literals so the agent and
//! SDK can't drift apart.

/// invoke a tool on an MCP server the agent is connected to, outside the LLM loop.
/// See `extensions::mcp::handle_call`.
