source410: literal 4.10 source reconstruction + BC++ 4.52 fleet toolchain archived

- BORLAND/: Borland C++ 4.52 (chosen over 4.5 by byte-match: CODE/RP/CW32.LIB
  is identical to 4.52's install lib). BCC32/TLINK32/TLIB/MAKE run natively on
  Win11; CODE/BT/OPT.MAK is the shipped BTL4OPT.EXE's exact flag recipe
  (extender = Borland PowerPack DPMI32, not Phar Lap TNT).
- restoration/source410/: the literal 1995-form reconstruction of the missing
  BT game source (never mixed into CODE/). Round 1-3 state:
  * 6 of 10 surviving original TUs COMPILE CLEAN under the period toolchain
    (BTMSSN, BTCNSL, BTSCNRL, BTTEAM, BTL4MODE, BTL4ARND) - first builds
    since 1996.
  * BT_L4/BTL4APP.CPP pilot reconstruction: 12/12 functions, Fail() lands on
    its binary-recorded line 400 exactly.
  * BT/BTCNSL.HPP: console wire IDs recovered from the binary's ctors
    (Killed=9, Damaged=10, ScoreUpdate=13, DeathWithoutHonor=15 [T1];
    TeamScore=12 flagged [T4]).
  * MUNGA/: 8 engine-header backfills back-dated from the BT412 WinTesla tree
    (VDATA numbering decomp-verified; AUDREND's OpenAL-era virtual removed -
    the period compiler is the drift detector).
  * Tooling: backdate.py (WinTesla->1995 header transform), compile410.sh
    (per-TU verification sweep under authentic OPT.MAK flags).
  * README: corrected roadmap - MECH.HPP is the capstone grown with the mech
    TU reconstructions; BTREG.CPP green = the header-family milestone.
