6ffcf77dd8 fix: Phase 3 — #25,28,29,41 token/AST/parser cleanup
Files modified (4):
  compiler/token/token.go — #25: Replace hand-rolled itoa with strconv.Itoa
    Fixes math.MinInt overflow bug in original implementation
  compiler/ast/ast.go — #29: Fix VarDecl.End() returning last var position
    Was returning Pos() (useless span info)
  compiler/parser/stmtreg.go — #28: Eliminate all 7 token array mutations
    rewriteAsIdent() modifies p.current only, not the token array
    Prevents backtracking corruption and improves safety
  compiler/lexer/lexer.go — Already clean from Phase 2

Issues resolved: #25 (MEDIUM), #28 (MEDIUM), #29 (MEDIUM), #41 partial (LOW)
Total fixed: 29/53

d7513eeb24 fix: Code review round 2 — race conditions, dead code, hardcoded paths
CRITICAL fixes:
- #1 vm.go: Mutex on libModules/dynamicFuncs global slices
  RegisterLibModule/RegisterDynamicFunc now thread-safe
  RegisterLibModules copies under lock, clears, releases
- #4 shutdown.go: Signal handler goroutine leak fixed
  Uses done channel + select for clean exit on normal shutdown

HIGH fixes:
- #7-8 gobridge.go: Remove dead if/else branches (both identical)
- #13-14 main.go: Remove hardcoded /mnt/d/harbour-core paths
  Use HB_INC env var + standard /usr/local/include/harbour only
- #15 main.go: Remove unused frbModSeq variable

MEDIUM fixes:
- #22 expr.go: Remove unused parts variable in parseInterpolatedString
- #51 macro.go: Remove var _ = fmt.Sprintf import guard
- macroeval.go: Remove unused lexer import and guard

Total fixed this session: 12/53 issues resolved
Remaining: 41 (CRITICAL: 1, HIGH: 9, MEDIUM: 16, LOW: 16)

7c61db70c3 fix: Critical code review fixes — race conditions, panic recovery, LTRIM/RTRIM
CRITICAL fixes:
- fileio.go: Add sync.Mutex to file handle table (race condition #2)
  allocHandle/getHandle/removeHandle thread-safe helpers
- goroutine.go: Add defer/recover to GoLaunch/GoLaunchBlock
  Goroutine panic no longer crashes entire process (#5)

HIGH fixes:
- strings.go: Implement proper LTrim (TrimLeft) and RTrim (TrimRight)
  Previously both aliased to AllTrim — silent semantic bug (#18)
- register.go: TRIM = RTrim (Harbour compatible)

From 53-issue senior code review.
Remaining: 47 issues (HIGH: 10, MEDIUM: 18, LOW: 16, CRITICAL: 3)

a2430fa44b docs: Strengthen Five Philosophy — full manifesto with real-world stories
Expanded from 180 lines to 450+ lines per language:
- Real failure stories: EU bank COBOL→Java (€200M), Brazil Clipper→Python (tax error)
- Deep Go analysis: 25 keywords vs 90+, no exceptions by design, hardware future
- AI paradox: code generation vs code understanding gap
- Detailed code comparisons: Go vs Five for discount calculation
- Five principles with battle scars from 30 years of xBase deployment
- Independence manifesto: zero-dependency code ownership
- Epilogue: what will future archaeologists find?

"The measure of a language is not what it can express,
but what it allows a stranger to understand."

409c82dd3c docs: Five Philosophy — the bible of why Five exists
The founding document of Five, written as a manifesto:
- Why 30 years of xBase code must not be discarded
- Why Go is the right foundation for the next 50 years
- Why human-readable code matters more in the AI era
- What was designed: 5 principles, 5 architectures
- The vision: living code that bridges past and future

"Code fades, but thought endures."

542373572f feat: MemRDD — in-memory database engine (Go map-based)
Complete in-memory RDD implementation:
- CRUD: Create, Append, GetValue, PutValue, Delete, Recall
- Navigation: GoTo, GoTop, GoBottom, Skip, BOF, EOF
- Index: CreateIndex (sorted slice + binary search), Seek (exact + soft)
- Bulk: Pack (remove deleted), Zap (clear all)
- Multi-open: shared table across work areas
- Driver registered as "MEMRDD", prefix "mem:"

Tests: 9 tests including 5000-record stress test
  Create, Append/Get/Put, Navigation, Delete/Pack, Zap,
  Index (string + numeric), Seek (exact + soft), Stress 5000, Multi-open

Use cases: temp tables, query results, pivot, caching
Performance: no disk I/O, no byte packing — pure Go slices

0828d17159 feat: Harbour RTL vs Go math comparison example + analyzer IMPORT fix
- examples/go_math_compare.prg: Side-by-side comparison of
  Harbour RTL (Abs, Sqrt, Round, Int, Max, Min, Log, Exp, Mod)
  vs Go math package (Sin, Cos, Pow, Pi, Floor, Ceil, Hypot, ...)
- Combined usage: normal distribution, compound interest, distance
- Analyzer: recognize IMPORT package names as valid identifiers
- Analyzer: add math RTL functions (ABS, SQRT, etc.) to known list

e04ae563ef test: 16 dynamic PRG tests — all new syntax works in FRB/runtime
Verifies every Five extension works in dynamic compilation:
- Multi-return (RETURN a,b + a,b := Func())
- DEFER (Go defer in PRG)
- Slice (a[2:4])
- Channel operators (ch <- val, <- ch)
- SPAWN / LAUNCH / GOROUTINE
- WATCH (channel multiplexing)
- ASYNC / AWAIT
- WITH TIMEOUT
- Nil-safe (?:)
- f-string interpolation
- CONST block
- PARALLEL FOR
- IMPORT + pkg.Func() (Go direct call)
- obj:Method() (Go object bridge)
- MacroEval (runtime expression evaluation)

All 16 tests PASS — dynamic PRG has full feature parity.

6b37cc19e4 test: 8 shutdown tests — EXIT, AtExit, WorkArea, panic-safe, statics
Tests verify:
- EXIT PROCEDURE auto-execution on shutdown
- Reverse module order for EXIT
- AtExit LIFO callback order
- WorkArea CloseAll on exit
- Panic in cleanup doesn't crash (safeCall)
- Shutdown runs exactly once (sync.Once)
- Static variables cleared
- Full sequence order: EXIT → AtExit → WA:Close → onExit

272576f6ce feat: Harbour-compatible VM shutdown sequence
Implements full cleanup on program exit (normal, Ctrl+C, crash):
- EXIT PROCEDURE auto-execution (reverse module order)
- AtExit callback registry (LIFO order)
- All WorkAreas auto-close (child before parent)
- Terminal restore (raw → normal) on signal/exit
- Static variables clear
- Signal handlers (SIGINT, SIGTERM) for clean shutdown
- shutdown.go: Harbour hb_vmQuit() 25-step sequence adapted for Five
- vm.go: Run() now calls Shutdown() via defer
- rawtty.go: terminal restore registered with shutdown system

d774f1598c docs: Fix readability docs — Five supports DEFER too
Five's DEFER is Go's defer in PRG syntax.
Same safety guarantee, but without if err != nil pollution.

b1a58724c8 docs: Add readability advantage — AI era code maintainability
Five's hidden strength: PRG code is readable by non-developers.
When AI generates code, humans must verify it.
Five's xBase syntax makes this possible.
