Adds options for controlling padding in agent session event streams. - Accept stream_options when creating a session and include_obfuscation when streaming its events - Expose optional obfuscation padding on session events - Keep event padding enabled by default

## Changes being requested Reduce AGENTS.md from 786 to 505 words (36%) by linking the existing contributor security and Python support policies, consolidating generated-file ownership, and shortening repeated prose. Retain the unique agent requirements, CODEOWNER/security regression gates, complete Python-version validation command sequence, automation isolation, and large-payload compatibility/test constraints. Preserve the generated-file-ownership anchor. ## Additional context & links Validation: - Completed basic diff and semantic-preservation review, including proxy security review, Python-floor changes, automation authority, and large-payload regression scenarios. - Verified all local file links and heading anchors; retained original section anchors. - Compared the validation shell block byte-for-byte with the original; unchanged. - Diff whitespace check passed. - No Python lint/build/runtime tests run: only AGENTS.md changed; repository lint/format scripts do not check this Markdown file.
