[instructions] Sync instruction files with release v0.74.8

Instructions Update - Synchronized with v0.74.8

This PR adds documentation for two safe-output operations that exist in code and the workflow schema but were missing from .github/aw/safe-outputs.md. Identified by comparing pkg/workflow/compiler_types.go (SafeOutputsConfig struct), pkg/workflow/safe_outputs_config.go (parser dispatch), and pkg/parser/schemas/main_workflow_schema.json against the current instructions.

Files Changed

• .github/aw/safe-outputs.md: added comment-memory and create-check-run sections.

Operations added

• comment-memory — Persist and update a managed memory comment on issues/PRs. Materializes memory content to files for agent editing and synchronizes edits back to a single managed comment after execution. Source: pkg/workflow/comment_memory.go, schema at line 4320.
• create-check-run — Create GitHub Check Runs to surface agent analysis results in the PR Checks UI. Requires checks: write permission. Source: pkg/workflow/create_check_run.go, schema at line 6818.

Audit Notes

• Only one commit landed since v0.74.8 (5288def, debug logging); no doc changes there to review. The drift this PR fixes pre-dates that commit but had not been reflected in the instruction files.
• Confirmed the deprecated create-agent-task (schema line 4997) is intentionally not documented — superseded by the already-documented create-agent-session.
• Confirmed create-code-scanning-alert (singular) is the correct YAML key by inspecting the parser (outputMap["create-code-scanning-alert"] in pkg/workflow/create_code_scanning_alert.go); the plural-suffix YAML struct tag in compiler_types.go is unused dead metadata, not a doc bug.

Size Audit

File	Before	After	Limit	Status
github-agentic-workflows.md	196	196	250 (hard)	OK
safe-outputs.md	1041	1070	1100 (target)	OK
syntax.md	964	964	1000 (target)	OK
triggers.md	165	165	200 (target)	OK
context.md	196	196	250 (target)	OK
cli-commands.md	268	268	400 (target)	OK

Validation

• Followed prompting best practices (imperative mood, minimal examples)
• Maintained technical tone and brevity
• Updated the correct sub-file for each change (safe-outputs.md, not the main file)
• No content duplication introduced between files
• File sizes within target limits
• Verified accuracy against current codebase (struct fields, parsers, schema)
