Pull request overview
Adds configurability for the Uvicorn server log level in the ADK CLI via UVICORN_LOG_LEVEL, with fallback to LOG_LEVEL and default info, addressing #1269.
Changes:
- Read
UVICORN_LOG_LEVEL(fallback toLOG_LEVEL, defaultinfo) and normalize it. - Pass the resolved log level into both
uvicorn.run()call sites (staticandruncommands).

uvicorn_log_level is derived from LOG_LEVEL/UVICORN_LOG_LEVEL without sanitizing/normalizing beyond .lower(). If LOG_LEVEL is set to a numeric value (which Python logging accepts) or either env var is set but empty/whitespace, this will pass an invalid log_level through to uvicorn.run(). Consider .strip() plus handling numeric levels (e.g., map 20→"info") and falling back to "info" when the value is empty/invalid.

Read the UVICORN_LOG_LEVEL environment variable (falling back to LOG_LEVEL, then 'info') and pass it to uvicorn.run() in both the 'static' and 'run' commands. This allows users to control uvicorn's log verbosity at deployment time without code changes. Fixes kagent-dev#1269 Signed-off-by: OpSpawn <opspawn@users.noreply.github.com>

Adds support for configuring the uvicorn server log level via UVICORN_LOG_LEVEL env var. Falls back to LOG_LEVEL, then info. Fixes #1269
