fix(capability): declare associative arrays before service registry port fallback

[vaibhavsrv]

Why this matters

In ods/scripts/build-capability-profile.sh, when the capability profiler runs without an active lib/service-registry.sh file, the script attempts to evaluate _LLM_PORT="${SERVICE_PORTS[llama-server]:-11434}". Because set -u is enabled and SERVICE_PORTS has not yet been declared as an associative array via declare -A, bash interprets the index llama-server as an arithmetic expression referencing an undeclared variable llama. This triggers a fatal llama: unbound variable error and crashes hardware capability profiling during standalone or isolated CLI executions.

This patch declares SERVICE_PORTS and SERVICE_HEALTH as associative arrays prior to inspecting or sourcing the service registry, ensuring that string keys evaluate safely under set -u even when the registry library is not loaded.

Validation

• Repro baseline: Executed build-capability-profile.sh in an isolated directory without lib/service-registry.sh; confirmed bash exited with code 1 and llama: unbound variable.
• Post-fix: Verified test_capability_unbound_ports.py passes with exit code 0; capability profiling completes successfully, generating capabilities.json with fallback port 11434.
• Capability suites: 1 passed. New-test Ruff, ShellCheck, and diff checks pass; new regressions wired into Linux CI.

Overlap check

• fix(env): probe .env keys literally in _env_set and mode-switch env_set #5819 (0xacee): Addressed macOS environment generation and safe escaping; touches ods/installers/macos/ with zero overlap in capability scripts.
• fix(cold-storage): create cold directory before archiving idle models #5861 (vaibhavsrv): Addressed directory creation in cold storage archiving; touches ods/scripts/llm-cold-storage.sh.
• fix(scripts): validate context length, port bounds, and control characters in render-runtime-configs #5056 (upstream): Touched Compose model definitions without altering capability profiling scripts.

Risk / AI disclosure

AI-assisted investigation, implementation and CLI regressions. This strengthens variable declarations in shell profiling utilities under strict mode, not runtime service admission. Independent human review and platform/runtime qualification remain gates. No running configuration, deployment or upstream merge changed.

Follow-up integration evidence

Composed with #5861 at 2a24f49 without conflicts. Production and test diffs passed together; capability and hardware classification checks remain intact.
Backlog composition was local-only (production/test diffs, excluding workflow/Makefile wiring); it is not an upstream merge or independent human approval. Declared live-review gates remain open.
