Fix escape code characters in CI pipelines

[Copilot]

Pull Request

Description
ANSI escape codes were appearing as plaintext in non-interactive terminals (CI pipelines, piped/redirected output), cluttering logs with sequences like \033[92m.

Modified color_logger.py to check sys.stdout.isatty() before applying color codes:

• Interactive terminals (TTY): Apply color codes normally
• Non-interactive (CI/pipes/files): Omit escape codes entirely

Additional Context
The fix is minimal - one import and one conditional check:

# Before
colored_message = f"{color}{message}{reset}"

# After
colored_message = f"{color}{message}{reset}" if sys.stdout.isatty() else f"{message}"

Verified with:

# Interactive: shows colors
python3 script.py

# CI/piped: no escape codes
python3 script.py | cat
python3 script.py > log.txt

qcom-build-utils/scripts/color_logger.py

Lines 51 to 59 in e966f5e

	def log(self, level, message):
	reset = "\033[0m"
	color = self.LEVEL_COLORS.get(level, "")
	level_str = self.LEVEL_STRING.get(level, ' ')
	colored_message = f"{color}{message}{reset}"
	timestamp = datetime.datetime.now().strftime("%H:%M:%S")
	self.logger.log(level, f"[{timestamp}] {level_str} : {colored_message if self.color_enabled else message}")

In this block of code, the log message is wrapped around color specific escape codes. Non interactive terminals don't understand these escape codes and hence they are printed in plaintext.
We can check for existence of an interactive terminal and proceed with our logging accordingly

 def log(self, level, message): 
     ....
     colored_message = f"{message}" if sys.stdout.isatty() else f"{color}{message}{reset}"
     ....
