feat: pretty default logs for build helper

[dobrac]

Example usages

The default log level is now INFO

await Template.build(template, {
  alias: 'complex-python-app',
  onBuildLogs: defaultBuildLogger(),
});

await AsyncTemplate.build(
    template,
    alias="complex-python-app",
    on_build_logs=default_build_logger(),
)

Template.build(
    template,
    alias="complex-python-app",
    on_build_logs=default_build_logger({ minLevel: "debug" }),
)

---

Note

Introduces pretty default build loggers for JS/Python SDKs, emits start/end build logs, and updates CLI templates/tests to use them.

• SDKs
  • JS SDK (packages/js-sdk):
    • Add defaultBuildLogger with colored output (chalk); new logger.ts.
    • Export LogEntry, LogEntryStart, LogEntryEnd, LogEntryLevel from template and root index.
    • Type updates: onBuildLogs?: (logEntry: LogEntry) => void.
    • TemplateBase.build now emits LogEntryStart/LogEntryEnd and structured info logs.
  • Python SDK (packages/python-sdk):
    • Add default_build_logger with pretty output (rich).
    • Introduce LogEntryLevel, LogEntryStart, LogEntryEnd; export via __init__.
    • Template.build/AsyncTemplate.build emit start/end logs and structured info logs.
    • Add pyrightconfig.json; update deps in pyproject.toml and lockfile.
• CLI (packages/cli)
  • Templates now pass loggers: TS onBuildLogs: defaultBuildLogger(), Python on_build_logs=default_build_logger().
  • Update expected fixtures accordingly.
• Tests
  • JS/Python build tests updated to use default logger; setup adjusted for new onBuildLogs signature.
• Dependencies
  • JS: add chalk.
  • Python: add rich (and new transitive packages).
• Changeset
  • Patch bumps for @e2b/python-sdk, e2b, and @e2b/cli.

Bug: Build Completion Logging Misleads on Failures

The build method's finally block always emits a "Build finished" log entry, even if an exception occurs during the build. This can be misleading when a build fails.
