Replace exponential-backtracking grammar with targeted optimizations:

- Add prattArithRest() Java loop for arithmetic (eliminates AddChain/MulChain method calls)
- Add prattExpressionRest() Java loop for boolean ops (eliminates XorExpression/AndChain)
- Replace LOOKAHEAD(ParenthesedFromItem()) syntactic scan with O(1) isParenthesedFromItemAhead()
  predicate — this was the root cause: it speculatively re-ran the full expression tower
  for every "(" in every FROM clause
- Gate LOOKAHEAD(5) UserVariable, LOOKAHEAD(2) NOT/PRIOR, LOOKAHEAD("(+)") Oracle join
  behind cheap token-kind checks so they don't scan on every expression
- Fix ComparisonItem: replace LOOKAHEAD(3) SimpleExpression() syntactic scan with semantic
  predicates for AnyComparisonExpression and RowConstructor
- Inline isComparisonOperatorAhead() into isConditionSuffixAhead() to eliminate redundant
  getToken(1) call on every parsed expression
- Fix isNestedSetOperationAhead() to handle arbitrary nesting depth (((SELECT) UNION ...))
- Fix isParenthesedFromItemAhead() edge cases: ((SELECT) JOIN ...), VALUES, EXASOL IMPORT
- Fix choice-conflict warnings in XorExpression/AndChain/MulChain/AddChain loops
  (outer LOOKAHEAD(2) grouping, {{ }} scoping for variable redefinition)
- Restore all previously passing tests broken by the committed 6.5ms branch

Result: 8ms → ~7ms on benchmark corpus

Pack separate bufline[] and bufcolumn[] arrays into a single long[]
(line in upper 32 bits, column in lower 32), halving array writes in
UpdateLineColumn which executes for every character read.

Add fast path in UpdateLineColumn for printable ASCII (c >= ' ' with
no pending newline), skipping the newline/tab switch statement for the
95%+ common case in SQL input.

Mark readChar, UpdateLineColumn, BeginToken, and backup as final to
enable JIT devirtualization and inlining.

Change ExpandBuff from linear growth (+2048) to exponential (2x),
reducing O(n^2) copying for large SQL statements. Remove the
Throwable catch that discarded stack traces.

Zero-dependency tests that scan compiled .class files and fail when any
method approaches the JVM 64KB bytecode limit, catching the problem
before ASM/JaCoCo instrumentation pushes it over the edge.

BytecodeSizeVerifier: classfile parser reading Code attribute sizes
  directly (no ASM dependency). Works as both CLI tool and library.

BytecodeSizeTest (JUnit 5):
- clinitMustFitWithinInstrumentationSafeLimit: targets <clinit> with
  20% headroom for instrumentation overhead
- allMethodsMustFitWithinInstrumentationSafeLimit: scans all methods
- criticalClassesMustBePresent: guards against silent test skip

Prevents regression of:
  org.objectweb.asm.MethodTooLargeException: Method too large:
    net/sf/jsqlparser/parser/CCJSqlParserTokenManager.<clinit> ()V
