feat: add IDFA Financial Architect to business plugins catalog

[mjunaidca]

Summary

• Moves the IDFA Financial Architect plugin from its standalone repo (panaversity/idfa-financial-architect) into the multi-plugin business catalog
• All internal paths use relative traversal (Path(__file__).parent.parent) — zero path edits needed inside the plugin
• Adds per-plugin CI workflows matching the islamic-finance pattern (evals on PR, zip packaging on release)

Changes

• idfa-financial-architect/ — full plugin directory (skills, evals, tests, examples)
• marketplace.json — added IDFA as second plugin entry
• README.md — added IDFA to catalog table, download section, license note
• .github/workflows/idfa-evals.yml — programmatic smoke test + structure validation on PRs
• .github/workflows/idfa-release.yml — zip packaging + GitHub Releases on idfa-v* tags
• Removed standalone marketplace.json from IDFA's .claude-plugin/
• Updated plugin.json repository URL to point to this repo
• Updated IDFA README.md install instructions

Verification

# Programmatic eval passes (row insertion robustness — no agent needed)
cd idfa-financial-architect && uv run evals/run.py --case row_insertion_robust -v
# Result: 1/1 cases pass (100%)

# Plugin structure validated
# marketplace.json: 2 plugins in catalog
# No Apache license references in IDFA dir (it's Proprietary)
