fix(rg): align -u ignore classes with --no-ignore

[chaliy]

Motivation

• Make -u/--unrestricted match --no-ignore semantics by disabling all per-class ignore toggles on the first -u so later positive flags only re-enable their intended classes.
• Fix bug where -u --ignore-dot unintentionally left VCS/exclude/global/parent ignore classes enabled, causing incorrect ignore-file loading.

Description

• Updated RgOptions::apply_unrestricted to set no_ignore_dot, no_ignore_exclude, no_ignore_global, no_ignore_parent, and no_ignore_vcs when no_ignore is first set.
• Added a differential test case unrestricted and ignore-dot only restores dot ignores to prevent regressions in partial re-enable behavior.
• Modified file: crates/bashkit/src/builtins/rg/mod.rs.

Testing

• Ran cargo test -p bashkit builtins::rg::tests -- --nocapture and the test run exercised the rg suite; the new/related rg tests passed while one unrelated existing differential test (diff_rg_matches_real_rg_cases) failed due to a timing-line mismatch.
• The added differential case for -u --ignore-dot executed and matched the expected output in the test run.
