PR Summary

Low Risk
Purely additive PoC CLI under pocs/ with no changes to existing application/runtime behavior; main risk is local file/envrc manipulation when users run the tool.

Overview
Adds a new pocs/agentprofiles-cli Node.js/TypeScript CLI (agentprofiles) that manages per-project profile directories for supported agent tools (e.g. Claude Code/OpenCode) and wires them into projects by generating/updating .envrc plus a managed .envrc.agentprofiles file.

Includes full packaging/build tooling (npm scripts, tsup build, ESLint/Prettier configs, lockfile), documentation/licenses, and basic test coverage with a shell smoke test that exercises add/set/unset and validates generated envrc blocks (including migration support from legacy .envrc.agent).
