cfcompare 0.1.0

• Initial version.
• Native R implementations of the Triply RObust Panel (TROP) estimator of Athey, Imbens, Qu & Viviano (2026).
• panel_compare() runs DID, SDID, SC, MC, TROP, gsynth and augsynth on one dataset and returns a common tidy ATT schema with shared plots.
• trop_matrix() provides a matrix-in form whose results can be numerically compared with the official Python trop matrix-in signature for direct cross-checking; verified to match the reference to numerical tolerance on the weighted-TWFE special case.
