Problem

Users who use both cfl (Confluence) and jtk (Jira) CLIs need to set duplicate environment variables:

export CFL_URL=https://mycompany.atlassian.net
export CFL_EMAIL=user@example.com
export CFL_API_TOKEN=token123

export JIRA_URL=https://mycompany.atlassian.net
export JIRA_EMAIL=user@example.com
export JIRA_API_TOKEN=token123

Since both tools authenticate against the same Atlassian account with the same credentials, this duplication is unnecessary.

Proposed Solution

Add ATLASSIAN_* env vars as a fallback layer. Lookup order (most to least specific):

CFL_URL → ATLASSIAN_URL
CFL_EMAIL → ATLASSIAN_EMAIL
CFL_API_TOKEN → ATLASSIAN_API_TOKEN

This allows users to set shared credentials once:

export ATLASSIAN_URL=https://mycompany.atlassian.net
export ATLASSIAN_EMAIL=user@example.com
export ATLASSIAN_API_TOKEN=token123

And override per-tool when needed (e.g., self-hosted instances at different URLs):

export ATLASSIAN_EMAIL=user@example.com
export ATLASSIAN_API_TOKEN=token123
export JIRA_URL=https://jira.corp.com
export CFL_URL=https://confluence.corp.com

Changes Required

Update internal/config/config.go:

• LoadFromEnv(): Check CFL_* first, then fall back to ATLASSIAN_*

Update documentation (README.md, CLAUDE.md) with new env vars.
