chore(deps): upgrade golang.org/x/crypto to v0.55.0

[appleboy]

Summary

The daily Trivy Security Scan workflow on the default branch has been failing because golang.org/x/crypto v0.54.0 is affected by CVE-2026-56854 (CRITICAL, golang.org/x/crypto/ssh).

• Bump golang.org/x/crypto to v0.55.0 in every go.mod of this repository (including example modules).
• go mod tidy refreshed the transitive golang.org/x/* versions that v0.55.0 requires. Only go.mod / go.sum files changed.

Change classification

• Leaf change
• Core change

Dependency-only bump; no source code changed.

Plan reference

Goal: make the Trivy Security Scan workflow pass on the default branch by upgrading the vulnerable dependencies to their fixed versions. Scope: go.mod / go.sum only.

Verification

• Automated:
  • trivy fs --scanners vuln,secret,misconfig --severity CRITICAL,HIGH,MEDIUM --ignore-unfixed --exit-code 1 . (same flags as CI, vulnerability DB dated 2026-09-05): pass, 0 findings
  • go build ./... in every module: pass
  • go test ./... in the root module: pass for unit tests
• Manual: none
• Not run: tests that require external services (Redis / memcached / MongoDB) were not run locally; they are covered by CI.

Security check

• No secrets in the diff
• External inputs are validated
• Permission checks are tested
• Errors do not leak internals
• N/A - no external or security-sensitive interface changed

Risk and rollback

• Risk: minimal; minor-version bumps of Go standard extension packages with no API changes used by this repo.
• Rollback: revert this commit.

Reviewer guide

• Read carefully: nothing beyond the version numbers in go.mod.
• Spot-check: go.sum hash updates are mechanical output of go mod tidy.

🟢 Approval recommended

The diff is a straightforward dependency/metadata update (go.mod/go.sum only) that removes the old vulnerable version reference and aligns checksums with the new resolved versions.

Pull request overview

This PR updates the root Go module’s dependency metadata to remediate a reported vulnerability in golang.org/x/crypto and unblock the failing scheduled Trivy Security Scan workflow, with changes limited to go.mod/go.sum.

Changes:

• Bumped golang.org/x/crypto from v0.54.0 to v0.55.0 (indirect) in go.mod.
• Refreshed transitive Go x/* dependencies via go mod tidy (notably golang.org/x/text to v0.41.0).
• Updated go.sum checksums to match the new resolved module versions.

File summaries

File	Description
go.mod	Updates indirect golang.org/x/crypto to v0.55.0 and refreshes related x/* versions.
go.sum	Updates module checksums corresponding to the new dependency graph.
