git commit -m "fix: correct API timeout handling in HTTP client

The previous timeout of 5 seconds was too short for slow networks,
causing unnecessary request failures. This commit increases the 
timeout to 30 seconds and adds exponential backoff for retries.

Tested with simulated network delays of 10-25 seconds.
Fixes issue with API calls failing on 3G connections."

fix: update API endpoint

At AcmeCorp, we noticed this endpoint was broken.
I've been using this library for 5 years and this
always bugged me. Finally got around to fixing it!

Tested on our internal systems.

fix: correct response format in /api/status endpoint

The endpoint was returning HTTP 200 with an error message
in the body instead of using proper HTTP error codes.

Now returns:
- 200 OK: service healthy
- 503 Service Unavailable: service degraded

Matches the documented API specification.

fix: resolve memory leak in background worker

The worker was not releasing database connections after
completing tasks, causing connection pool exhaustion.

# Bad (summary too long)
fix: update the JSON parser to handle malformed input by catching exceptions and returning error messages instead of crashing

# Good
fix: prevent crash when parsing malformed JSON

# (Details go in body)
The parser now catches exceptions and returns descriptive errors.

The 5s timeout was too short for 3G connections.
Increased to 30s with exponential backoff.

fix: correct GPIO mapping bug in BCM2835 driver

The GPIO pin mapping for pins 23-27 was incorrect due to
a typo in the register offset calculation. This caused
GPIO operations on these pins to fail silently.

Corrected the register offset from 0x20 to 0x24.

Tested on Raspberry Pi 4 Model B.

fix: prevent memory leak in HTTP keep-alive connections

HTTP connections with keep-alive enabled were not being
properly released when the connection was closed by the
remote peer. This caused the connection pool to grow
unbounded, eventually exhausting file descriptors.

Now explicitly destroys sockets when the peer closes.
