chore: migrate CODEOWNERS from individual usernames to GitHub teams

[jasonqinzhou]

Summary

• Replaces long per-line individual username lists with @ai-dynamo team references throughout CODEOWNERS
• All previous owners are preserved — every new entry is a strict superset of the original
• Adds a comment block at the top documenting the team→member mapping for easy reference

New team structure

Team	Members	Role
aic-core	tianhaox, jasonqinzhou, Arsene12358, simone-chen, Harrilee, ilyasher	Broad cross-cutting SDK/infra owners
aic-sglang	xutizhou, AichenF	SGLang backend + collector
aic-vllm	ilyasher, davilu-nvidia	vLLM backend + collector
aic-systems	YijiaZhao	Systems, data files, comms collector
aic-automation	Ethan-ES	CLI, eval, generator, tools/automation
Devops	anish-shanbhag, ilyasher	Docker, CI/CD, infra (already exists)
contributors-aiconfigurator	everyone	Default catch-all (already exists)

⚠️ Action required before merging

The 5 new teams must be created in the ai-dynamo GitHub org first, otherwise team references will resolve to nobody and PRs won't auto-request reviewers:

1. Go to https://github.com/orgs/ai-dynamo/teams
2. Create each team: aic-core, aic-sglang, aic-vllm, aic-systems, aic-automation
3. Add the members listed above to each team
4. Verify contributors-aiconfigurator is (or becomes) a subteam of the org-wide all-NVIDIANs team

Why

• PRs were being spammed with review requests from coupled components sharing individual owner lists
• Adding/removing team members previously required editing many CODEOWNERS lines
• @xutizhou (Xuting ZHOU) was missing from broad coverage — now included via aic-sglang

Walkthrough

The pull request reorganizes repository code ownership from individual contributors to team-based groups, updates a TensorRT-LLM CLI template to include a backend field in cache transceiver configuration, and introduces comprehensive unit tests for the template's argument generation.

Changes

Cohort / File(s)	Summary
GitHub Configuration .github/CODEOWNERS	Reorganized ownership mappings to consolidate individual contributor assignments into team-based groups (e.g., @ai-dynamo/aic-core, @ai-dynamo/aic-sglang, @ai-dynamo/aic-vllm), covering src and auxiliary directories.
TensorRT-LLM Backend Template & Tests src/aiconfigurator/generator/config/backend_templates/trtllm/cli_args.j2, tests/unit/generator/test_trtllm_cli_args.py	Added backend: 'DEFAULT' field to cache_transceiver_config in CLI template and introduced 215 lines of regression tests verifying cache transceiver handling, CLI argument mappings, and engine argument overrides.

Poem

🐰 Hops with glee at ownership's new way,
Teams now gather, groups hold sway,
Templates tweaked with defaults bright,
Tests ensure the cache flows right! ✨

⚠️ Potential issue | 🟡 Minor

Finish the team-only migration on /collector/sglang.

This entry still names @davilu-nvidia directly, so this path is still tied to individual membership churn and no longer matches the team-based ownership goal of this PR.
