Pass 1 now records every field and method signature (access, type,
parameter types) in bank-1 member and parameter tables, rejects duplicate
fields or methods per type, invalid init/destroy shapes (E151/E152, D122),
and `var` after a method statement or inside a block. Each signature and the
program open a typed local scope. Pass 2 scans statement lines: unqualified
names must be locals, parameters, or fields of the enclosing class (D123),
and member chains through locals, fields, self, new, calls, and indexing
report unknown members (E061) and private access (E120) at the member.

The parser test PRG grew past $4000 and crashed: mmu_init copies the COMMON
load image in the system mapping, where BASIC ROM hides $4000+. COMMON now
loads right after STARTUP and mmu.s asserts both stay below $4000.

Verified in x128: 28 fixtures, member tables against a source-derived
oracle, privacy and scope mutations caught; map, source, lexer, names, and
diagnostics suites pass on the new layout.

src_load reads a SEQ file from device 8 once into a bank-1 cache (D118).
It enforces the 80-byte line, 599-line, and 18,999-byte limits as bytes
arrive and reports stable codes with exact positions. src_rewind and
src_next_line replay the cache one logical line at a time for every pass.
diskio.s wraps the KERNAL file calls; channels close on every path.

Verified in x128 with a 1581: eight fixtures, including the exact limits,
each limit error, a missing file (DOS 62), and a missing final $0D, all
match host-computed line counts, Fletcher-16 checksums, and positions.
Adds a shared PowerShell test library for x128 scripts.

Add cfg/compiler.cfg, the production mmu.s, c128.inc, and the test mailbox,
proven by a capacity-checking skeleton in x128:

- 8K bottom common RAM, shared code at $1300, private zero page at bank 0
  page $1A via P0, bank-1 tables at $2000-$BFFF, test mailbox at $1BF0
- ld65 rejects overflows of the ZP, COMMON, MAIN, SWSTACK, and TABLES areas
- a CIA #2 timer NMI taken under bank 1 with the private zero page returns
  cleanly through the NMI guard (closes the E01-S03 NMI risk)
- decision D117 records the map; RESTORE is ignored while compiling

Also pin newLang/ to LF in .gitattributes. A branch switch under
core.autocrlf had rewritten the byte-exact fixtures with CRLF.

Nova128 is an object-oriented language with an on-machine C128 compiler.
This adds the spec, decisions, architecture, backlog, and story claims,
plus the grammar fixtures (E00-S02), disk-image builder (E07-S01), and
the x128-verified platform probes:

- E01-S01 minimal native PRG
- E01-S02 MMU/common-RAM probe. With bottom common on, a P0/P1 pointer
  aimed at bank 1 lands in bank 0 at the translated page. The verifier
  traces every MMU write in the probe window.
- E01-S03 KERNAL wrapper (kcall). CHROUT, drive status, and a
  device-not-present failure work from bank 0 and bank 1 mappings.
  A/X/Y/C/ST are preserved and the MMU state is restored exactly.
- E01-S04 40/80-column display and clock probe
