Pull request overview

This PR updates the restic wrapper to support streaming/progress-style output by capturing in-flight command stdout from go-sh, adding status parsing helpers, and exposing a StatusSince API to retrieve incremental progress for a given backend/repository. It also updates wrapper copy semantics to better support concurrent execution and adjusts repository integrity handling to return stats even for certain “corrupted repo” cases.

Changes:

• Update vendored gomodules.xyz/go-sh to buffer per-command output (thread-safe buffers) and expose CurrentOutput.
• Add restic status parsing (ResticStatus, statusSince, sanitizers) plus unit tests; expose ResticWrapper.StatusSince.
• Remove circbuf dependency; deepen wrapper copy logic; tweak env setup and integrity verification behavior.

go.mod:59

• The commented replace with an absolute developer path should not be committed; it’s easy to accidentally uncomment during local work and it also leaks a machine-specific path into the module metadata.

//replace gomodules.xyz/go-sh => /home/anisur/go/src/gomodules/go-sh

We intentionally keep the logger without verbose because in our case the backup pod will run only once. There's no way to set verbose, and in one shot we don't want to lose any debug info.

No need, we handled the timeout with nil check.
