fix: hoist our/state declarations in statement modifiers (if/unless)

[fglock]

Summary

• Fix our and state variable declarations with statement modifiers (if/unless)
• The parser's handleStatementModifierWithMy only handled my declarations, causing our $DEBUG = 0 unless defined $DEBUG to fail under use strict with "Global symbol requires explicit package name"
• Extended the check to handle my, our, and state uniformly by hoisting the declaration before the condition: our $X = EXPR unless COND → (our $X, COND || ($X = EXPR))
• This unblocks Template Toolkit 3.102, which uses this pattern in 16+ .pm files — Makefile.PL now runs successfully
• Updated dev/modules/template.md with Fix 10 and current status

Files changed

File	Change
StatementResolver.java	Extended handleStatementModifierWithMy to handle our/state
statement.t	Added 4 tests for our/state with if/unless modifiers
template.md	Documented Fix 10 and updated remaining failures section

Test plan

• make passes (all unit tests green)
• ./jperl -e 'use strict; our $X = 1 unless defined $X; print "ok\n"' works
• ./jcpan -t Template gets past Makefile.PL and runs full test suite
• New unit tests cover our with unless, our with if, our preserving pre-defined values, and state with unless

Note on remaining Template Toolkit failures

After this fix, 85/106 Template Toolkit tests pass. The 21 failing tests are all caused by premature DESTROY firing on Template::Context — a separate refCount tracking issue being fixed on another branch.
