Brendan Robert 3d359f0a0e Add hardware acceleration for scalb, compXY, and annuityXY functions
Implemented hardware-accelerated versions of three additional functions:

- scalb(x, n): Binary scale operation (x * 2^n) using pow2X and mul
- compXY(rate, periods): Compound interest ((1+rate)^periods) using powXY
- annuityXY(rate, periods): Annuity calculation using powXY

This brings the total hardware-accelerated functions from 28 to 31 out of
40 total SANE operations (78% coverage). These functions leverage the
existing hardware-accelerated powXY implementation, combined with
mathematical identities to avoid SANE fallback.

All functions maintain full API compatibility and automatically fall back
to SANE if MegaFlash hardware is not available.

Updated documentation to reflect new accelerated function count and
reorganized function categories.

The PLASMA Environment has evolved: PLEIADES

PLASMA has grown from a language compiler to a full featured interactive environment for developing and running applications on a 6502 computer. Currently the Apple // series and the Apple /// are fully supported. With the addition of FORTH and LISP to the PLASMA ecosystem as well as support for assembly programming with EDASM and even a bugfix so AppleSoft can run from the PLEIADES command line, a new designation for the expanded functionality seems in order. PLEIADES incorporates many feature improvements and bug fixes from the previous PLASMA 2.11 release. Here a some of the biggest updates:

  1. Increase evaluation stack size to 32 entries for more complex algorithms
  2. Support longer lines and line continuations in PLASMA compiler
  3. Add 80 column (and greater) video mode to text editor and console I/O
  4. Increase editor max line length to 127 characters
  5. Greatly improve text loading performance of text editor
  6. PLVM, the Portable PLASMA VM, now runs modules with 6502 code
  7. Bug fixes and performance improvements to FORTH and LISP interpreters
  8. Suite of libraries and utilities for Double Hires GRaphics development
  9. Simple command file execution

The combination of all these enhancements make PLEIADES an efficient environment for programming and interacting with a 6502 computer.
