build(deps): update crawlkit to v0.14.3

[steipete]

Summary

• update direct dependency github.com/openclaw/crawlkit from v0.14.2 to the stable v0.14.3 GitHub release
• accept Crawlkit's compatible SQLite stack refresh (modernc.org/sqlite v1.54.0, matching libc/ccgo, and go-isatty v0.0.23)
• keep every other direct dependency at its already-current stable version

Proof

• Crawlkit v0.14.3 is a non-draft, non-prerelease GitHub Release resolving to commit d3ca116e7461c695b86c3ae6c2ed1ad65b89956d.
• go test -count=1 ./... — pass; filtered coverage 85.3%
• go test -count=1 -race ./... — pass
• real built CLI help/version/metadata/status/TUI smoke — pass
• golangci-lint, vet, staticcheck, deadcode, gofumpt, gosec — pass
• module verification and tidy idempotence — pass
• govulncheck — zero called vulnerabilities
• GoReleaser snapshot — all six targets pass
• gitleaks history/directory scans and shell syntax — pass
• Docker build plus version/help/git smoke — pass
• .agents/skills/autoreview/scripts/autoreview --mode local — clean; no accepted/actionable findings

Risk

Low. The Crawlkit release changes its own release/dependency infrastructure; Discrawl's full runtime and packaging gates pass unchanged.
