chore(rust): standardize strip = true across all Rust crates #177

Description

Standardize strip = true in [profile.release] across all Rust crates to reduce container image size and prevent debug symbol leakage in production binaries. Currently only video-to-gif sets this explicitly; the other 9 crates ship with default debug symbols in release builds.

The CI env var override (#168) provides the alternative build path when debug information is needed for diagnostics or profiling.

Acceptance Criteria

• All Rust crates have [profile.release] strip = true in their Cargo.toml
• Container images built from these crates produce smaller binaries
• CI env vars from ci(rust): add CI environment variables to preserve debug info in release builds #168 override strip = true to preserve debug info in CI builds
• Existing video-to-gif configuration is unchanged (already compliant)

Implementation Guidance

Add to each crate's Cargo.toml that does not already have it:

[profile.release]
strip = true

Crates to update (9 of 10 — video-to-gif already has this):

• src/500-application/500-basic-inference/
• src/500-application/501-rust-telemetry/
• src/500-application/502-rust-http-connector/
• src/500-application/503-media-capture-service/
• src/500-application/505-event-processor/
• src/500-application/506-open-telemetry-collector/
• src/500-application/507-ai-inference/
• src/500-application/508-ai-edge-inference-crate/
• src/900-tools-utilities/900-mqtt-tools/

Verify with cargo build --release that the output binary has no debug sections:

file target/release/<binary_name>
# Should show "stripped" or "not stripped" accordingly
