Linux reference-frame set for all 21 levels and the cross-platform golden
rule (D521); golden tooling made non-destructive (D524); the gate pins a
canonical in-tree save (D529) and the PRNG seed (D532); the capture tool's
per-level re-pin bug fixed and the Linux set re-captured under the
canonical save (D530, D531); no-arg verify.sh exits non-zero. README and
docs visual/consolidation passes; the 15 MB preview gif replaced by stills.

v0.3.0 silently wiped all v0.2.x saves on first launch: stored slot CRCs
are fingerprints of the PRNG that wrote them, and D284 changed the PRNG.
One-time migration in the eeprom shim's read path (block 4 only): a slot
that fails the current-CRC check but validates under the legacy PRNG is
re-stamped with current-PRNG checksums before fileValidateSaves sees it,
then persisted once. Runs before geEepromPatchAllCheats so cheat patches
never reach the file. Corrupt/fresh slots untouched (game's own wipe path).
- port/src/legacycrc.c: isolated file carrying the deliberately-wrong
pre-D284 PRNG (verbatim from 0de99b4d^, reviewer-verified bit-exact) +
lockstep copy of the crc.c loop; header says when it may be deleted.
- tools_pc/d295_crc.py: reference CRC model, bit-exact vs compiled C for
both PRNGs (used to verify migrated files).
Verified: user's #87 artifact migrates 5/5 slots with progress intact and
is idempotent on relaunch; native post-fix saves, corrupt slots, and fresh
eeps all behave per design; 21/21 sweep PASS.
