perf(config): eliminate double URL parse in validate_base_url

Extract `redact_parsed_url()` to accept an already-parsed URL, so `validate_base_url` parses once and reuses the result. The string-based `redact_url()` is kept for the parse-error fallback path only. Also removes an unused `safe_url` binding that survived the refactor.

fix(security): redact credentials from URL validation error messages

 //! Regression and unit tests for shell command risk-level classification
 //! (issue #172, PR #368).
 //!
 //! These tests live here (instead of inline in `src/tools/builtin/shell.rs`)
 //! because the project's no-panics CI check scans `src/**/*.rs` for
 //! `assert_eq!` / `assert_ne!` / `.unwrap()` in added lines.  All assertions
 //! on the public `ShellTool` API belong here.
 //!
 //! All tests access the shell tool through the public `ToolRegistry` +
 //! `Tool` trait surface (`risk_level_for`, `requires_approval`).
 //!
 //! ## What is tested
 //!
 //! 1. **Risk level tiers** (`High`, `Medium`, `Low`) for representative commands.
 //! 2. **Word-boundary matching** — commands whose names are substrings of other
 //!    words must not be misclassified.
 //! 3. **Pipeline aggregation** — the whole pipeline takes the maximum risk of
 //!    its segments.
 //! 4. **Redirect bypass regression** — Low-risk commands with shell redirections
 //!    must return `UnlessAutoApproved`, not `Never`.
 //! 5. **`git push` regression** — non-force push is explicitly `Medium`; force
 //!    variants remain `High`.
 //! 6. **`risk_level_for` trait method** — delegates to classify_command_risk.
