Add tooling pattern: Runtime.exec(String) to ProcessBuilder arguments

[Copilot]

Adds the requested tooling/runtime-exec-to-process-builder pattern contrasting Runtime.exec(String) command-string tokenization with an explicit ProcessBuilder argument list.

// Command string
Process process = Runtime.getRuntime()
        .exec("git show " + revision);

// ProcessBuilder
Process process = new ProcessBuilder(
        "git", "show", revision)
        .redirectErrorStream(true)
        .start();

Content

• content/tooling/runtime-exec-to-process-builder.yaml — jdkVersion: 5, difficulty: intermediate, support.state: available. Both approaches predate/ship in JDK 5, so labels are descriptive (Command string / ProcessBuilder) rather than version-based.
• Tags tooling + security (both already in tags.properties); docs link to ProcessBuilder and Runtime.exec(String).
• related: concurrency/process-api, io/inputstream-transferto, security/security-manager-migration.

Navigation

• Inserted between tooling/junit6-with-jspecify and language/anonymous-classes-to-lambdas; both neighbours' next/prev updated to keep the global chain reciprocal.

Proof

• proof/tooling/RuntimeExecToProcessBuilder.java runs the modern snippet, drains stdout and waits for exit — CI executes proofs rather than only compiling them.

Translations

• Partial translations for all 13 non-English locales, limited to the translatable fields (title, oldApproach, modernApproach, summary, explanation, whyModernWins, support.description).

Social

• social/queue.txt and social/tweets.yaml regenerated without --reshuffle, so only the new entry is appended; social/state.yaml untouched.

• Fixes [Pattern] Runtime.exec(String) to ProcessBuilder arguments #207
