PHLEGM v8 r85 — External three-script bootstrap revision normalization

Checkpoint and revision are aliases for one numeric field.
Extracted cfg/<$project>.master.phlegm fields checkpoint.current and revision.current are
normalized from optional r/R-prefixed values to numeric digits before compiler launch.
checkpoint.current takes precedence over revision.current, including if empty.
Empty checkpoint values remain empty; GUI / filename output alone adds the r prefix.
Original Developer ZIP remains unchanged during bootstrap extraction.
The bootstrap supports old -85 and new -r85 Developer archive names, logs canonical
revision metadata, and keeps the canonical 3 external launchers.
Source from the preceding checkpoint and all core compiler/UI files are preserved.
Requires native Windows/Linux build validation; only structural checks available here.
