chore(docker): verify tool downloads and pin build inputs

Stage the recon binaries in a build-platform "tools" stage and verify each
release archive against the checksums file of its own GitHub release (exact
asset name, sha256), failing the build when the entry is missing or does not
match: nuclei v3.11.1, httpx v1.12.0, subfinder v2.17.0, katana v1.8.0,
ffuf v2.3.0, dalfox v3.2.4. sqlmap is cloned at tag 1.9.9 and checked
against commit cceda39208b5aad478de2c3f731df4239d9881f6 before .git is
removed. The runtime stage copies /out/ and /opt/sqlmap from that stage.

Install Node v22.23.4 from the official nodejs.org tarball verified against
SHASUMS256.txt instead of piping the NodeSource setup script into bash.

Pin @playwright/mcp@0.0.83, @playwright/cli@0.1.22 and playwright@1.64.1
instead of @latest.

amd64 and arm64 are mapped explicitly; any other architecture fails the
build. dalfox --version no longer ignores failures.

Carries over the Dockerfile part of #127 by stevenAthompson.
