v1.88.1.0 fix: harden credential boundaries and owned state (#2942)

* fix(settings): preserve symlinked settings targets

Resolve the selected target for locking, mutation, backup, and rollback; refuse target changes and preserve private modes. Addresses #2830.

* fix(redact): bind masking to original detected spans

Inspired by #2929's anchored-span diagnosis; independently implemented using normalization offsets. Addresses #2930 and the relocation portion of #2912 without changing detection sensitivity.

* fix(evals): exclude operator credentials from prefix admission

Adapts the credential-suffix screen proposed in #2636, with real launched-child regression coverage and deliberate provider-auth exceptions.

* fix(artifacts): retain custom allowlist rules on reinitialization

Preserve the exact user-owned suffix and publish only a successfully assembled replacement. Independently implements the repair reported in #2907.

* test(cso): verify exact masked reads and unmaskable payload refusal

* fix(cso): preserve exact filesystem identities through lease recovery

Preserve 64-bit device/inode identity and nanosecond race checks. Add native NTFS lifecycle coverage for #2927; retain ambiguous legacy-state refusal without claiming Windows PID-reuse recovery is resolved.

* fix(redact): bind pre-push scans to destination and preserve seam context

Uses #2935 (bd07318) as source evidence for push-target range and slice-overlap defects. Independently implemented; no cherry-pick or release metadata adoption.

* test(ci): gate native agent ownership and settings links on macOS

* fix(browse): bind agent lifetimes and cleanup to owned generations

Uses #2931 by Chris Hutton / Claude Fable 5.1 as attributed design input; independently implemented without broad sweeps or copied code. Keep uncertain children and locks rather than deleting foreign state.

* test(ci): include concurrent shutdown controls in the native macOS gate

* v1.88.1.0 fix: harden credential boundaries and owned state

* fix(redact): preserve target provenance and scan boundary semantics

* test(artifacts): read managed rules from atomic allowlist assembly

* fix: preserve native exit observations and fixture prerequisites

* fix: preserve UTF-16 offsets through redaction normalization
