5a62ceaa99 refactor: extract safety module into ironclaw_safety crate (#1024)
* refactor: extract safety module into ironclaw_safety crate

Move prompt injection defense, input validation, secret leak detection,
and safety policy enforcement into a standalone crate under crates/.
The safety module was a leaf dependency with no async, no database, and
no other ironclaw traits — only pure computation with pattern matching.

SafetyConfig (2 fields) moves into the crate; env-var resolution stays
in ironclaw's config module as a free function. src/safety/mod.rs becomes
a thin re-export so all existing `crate::safety::*` imports keep working.

* docs: update CLAUDE.md for ironclaw_safety crate extraction

Add guidance to migrate imports from crate::safety to ironclaw_safety
when touching files. Update project structure to reflect crates/ dir.

* refactor: move safety fuzz targets into ironclaw_safety crate

Split fuzz infrastructure:
- crates/ironclaw_safety/fuzz/ — 5 safety-only targets (sanitizer,
  validator, leak_detector, credential_detect, config_env) depending
  only on ironclaw_safety for faster builds
- fuzz/ — keeps fuzz_tool_params which needs ironclaw::tools

Add seed corpus files (51 total) covering each pattern family:
sanitizer injection patterns, validator edge cases, leak detector
secret formats, credential detect HTTP param shapes.

Add new fuzz_credential_detect target exercising
params_contain_manual_credentials with arbitrary JSON.

* fix: address PR review — single-pass XML escaping and versioned path dep

Rewrite escape_xml_attr from chained .replace() to single-pass char
iteration (O(n) instead of O(4n) with intermediate allocations). Add
version = "0.1.0" to ironclaw_safety path dep to satisfy cargo-deny
wildcards = "deny".
