feat(tokenjuice): Rust port of terminal-output compaction engine (#644)

* feat(tokenjuice): implement core functionality for terminal-output compaction engine

- Introduced the `tokenjuice` module, which includes the classification and reduction of tool outputs based on JSON-configured rules.
- Added new dependencies for Unicode handling: `unicode-segmentation` and `unicode-width`.
- Implemented the `classify` module to match tool execution inputs against predefined rules, enhancing the ability to process and summarize terminal outputs.
- Created a comprehensive set of types and utilities for managing tool execution inputs and classification results.
- Established a built-in rule set for common tools, improving the initial setup and usability of the `tokenjuice` engine.
- Enhanced testing framework with integration tests to ensure the accuracy of output compaction and classification.

These changes lay the groundwork for a robust terminal-output management system, facilitating better interaction with various tools and improving overall user experience.

* feat(tokenjuice): implement tokenjuice module for terminal output compaction

- Introduced the `tokenjuice` module, which includes functionality for classifying and reducing terminal output based on JSON-configured rules.
- Added new dependencies: `unicode-segmentation` and `unicode-width` to support text processing.
- Created a new `classify.rs` file for rule classification logic, including matching helpers and scoring functions.
- Implemented a `reduce.rs` file to handle the main reduction pipeline and text normalization.
- Established a structured approach for loading and compiling rules from multiple sources, including built-in and user-defined rules.
- Added integration tests to ensure the correctness of the output reduction process.

These changes enhance the application's ability to manage and compact verbose tool outputs, improving overall efficiency and user experience.

* test(tokenjuice): enhance test coverage for classification and reduction logic

- Added a series of unit tests to `classify.rs` to validate the behavior of tool name filters and argument matching, ensuring correct classification of tool executions.
- Introduced tests for edge cases in `reduce.rs`, including command tokenization and normalization of execution inputs, to improve robustness against various input formats.
- Expanded tests in `builtin.rs` to cover duplicate ID reporting and compile issues, enhancing error handling and reporting mechanisms.
- Implemented additional tests in `compiler.rs` to verify regex handling in rule definitions, ensuring invalid patterns are correctly ignored.

These enhancements improve the overall test coverage and reliability of the tokenjuice module, facilitating better maintenance and future development.

* test(tokenjuice): add edge-case tests for gh table and reduction pipeline

* style(tokenjuice): apply cargo fmt

* feat(tokenjuice): wire into agent tool loop output compaction

Add `tokenjuice::compact_tool_output` helper and call it in the agent
tool loop after credential scrubbing (and on error paths with exit=1),
before any optional payload_summarizer. Derives argv/command
heuristically from JSON tool arguments (command / args / argv / cmd
shapes) so shell-wrapping tools still match upstream family rules
(git/*, package/*, tests/*, etc.). Pass-through safe: outputs under
512 bytes or where compaction saves <5% are returned untouched.

* fix(tokenjuice): address coderabbit review comments

- classify: derive command from argv join when input.command is unset,
  so commandIncludes* rules still match argv-only callers
- rules/loader: log read_dir / file_type / read_to_string failures at
  debug level so permission or filesystem issues are observable rather
  than silently skipped
- text/ansi: add trace log at strip_ansi entry/exit with lengths (no
  text content) per the project debug-logging rules
- tests: remove orphan src/openhuman/tokenjuice/tests/integration.rs
  which was never wired into any module declaration; the real fixture-
  parity runner lives at tests/tokenjuice_integration.rs and asserts
  hard when the fixtures directory is missing

Vendored-rule issues (docker-ps / kubectl-describe / git/branch /
grep casing / counter-pattern overbreadth / etc.) come from upstream
and are left as-is; this module is a straight port of the upstream
rule set and should not fork from it in v1.

+//! # TokenJuice — terminal-output compaction engine
+//!
+//! Rust port of [vincentkoc/tokenjuice](https://github.com/vincentkoc/tokenjuice).
+//!
+//! Compacts verbose tool output (git, npm, cargo, docker, …) using
+//! JSON-configured rules before it enters an LLM context window.
+//!
+//! ## Quick start
+//!
+//! ```rust
+//! use openhuman_core::openhuman::tokenjuice::{
+//!     reduce::reduce_execution_with_rules,
+//!     rules::load_builtin_rules,
+//!     types::{ReduceOptions, ToolExecutionInput},
+//! };
+//!
+//! let rules = load_builtin_rules();
+//! let input = ToolExecutionInput {
+//!     tool_name: "bash".to_owned(),
+//!     argv: Some(vec!["git".to_owned(), "status".to_owned()]),
+//!     stdout: Some("On branch main\n\tmodified:   src/lib.rs\n".to_owned()),
+//!     ..Default::default()
+//! };
+//! let result = reduce_execution_with_rules(input, &rules, &ReduceOptions::default());
+//! println!("{}", result.inline_text);
+//! // → "M: src/lib.rs"
+//! ```
+//!
+//! ## Scope (v1 — library only)
+//!
+//! This module is purely a library.  It has no JSON-RPC surface, no CLI, and
+//! no artifact store.  Those surfaces can be layered on later when a caller
+//! inside `openhuman` needs them.
+//!
+//! ## Three-layer rule overlay
+//!
+//! Rules are loaded from three sources in ascending priority order:
+//! 1. **Builtin** — vendored JSON files embedded via `include_str!`.
+//! 2. **User** — `~/.config/tokenjuice/rules/` (loaded from disk).
+//! 3. **Project** — `.tokenjuice/rules/` relative to `cwd` (loaded from disk).
+//!
+//! When two layers define the same rule `id`, the higher-priority layer wins.

+
+## File naming convention
+
+Upstream files live in subdirectory paths like `git/status.json`.  Because we
+embed all rules in a single directory here, `/` in the id is replaced with `__`
+in the filename (e.g. `git/status.json` → `git__status.json`).
+
+## Rules vendored
+
+**96 rules** are vendored here, representing the complete set of generic rules
+from the upstream repository as of 2026-04-17.
+
+### Exclusions
+
+The `src/rules/openclaw/` subdirectory in upstream is **not** vendored.  Those
+rules (`openclaw/sessions-history`, etc.) are specific to the upstream author's
+proprietary OpenClaw tooling and are not generic enough to include in the
+OpenHuman builtin set.  The `fixtures/` subdirectory is also excluded — fixture
+files are test-only and carry no runtime behaviour.
+
+### Adding more rules
+
+Additional rules from the upstream repository can be added by:
+
+1. Copying the JSON verbatim into this directory using the `family__name.json`
+   naming convention.
+2. Adding the corresponding `(id, include_str!(...))` entry to
+   `rules/builtin.rs`, keeping the list alphabetically ordered by id.
+3. Running `cargo check` and `cargo test tokenjuice` to confirm the new rule
+   compiles cleanly.
