974964719c Convert all static scratch buffers to thread_local
43 static scratch-buffer arrays across 21 files (5 in mux/src, 38 in
mux/modules/) changed from `static` to `thread_local`. Under the
current single-threaded evaluator this is a zero-behavior-change swap
— `thread_local` storage has the same lifetime and zero-allocation
properties as `static` — but each thread gets its own copy, which
makes these functions safe for a future multi-threaded evaluator
without any locking.

Read-only constant tables (`aRadix64`, `aRadixPenn36`,
`aRadixPenn64`, `Empty`) left as `static` because they are immutable
shared data.

Affected areas:
  net.cpp        — queue_string co_buf, trimmed_site, dump_users NameField
  signals.cpp    — signal_desc
  stubslave.cpp  — Stub_PipePump
  attrcache.cpp  — sqlite_attr_buf
  boolexp.cpp    — parsestore
  command.cpp    — preserve_cmd, SpaceCompressCommand, LowerCaseCommand
  comsys.cpp     — NewTitle, Buffer, temp
  db.cpp         — tbuff, Buffer (x2)
  flags.cpp      — buff
  funceval.cpp   — textbuff
  functions.cpp  — TimeBuffer64, TimeBuffer80, Buffer
  help.cpp       — Line, Buffer
  mail.cpp       — aFolders, Buffer, res, szFittedMailAliasDesc
  match.cpp      — buffer
  player.cpp     — szSalt, buf (x2), buff
  plusemail.cpp   — buf
  predicates.cpp — Buf (x2), pName
  session.cpp    — szFittedDoing
  set.cpp        — pRestrictedKeyText
  unparse.cpp    — buf, boolexp_buf
  mail_mod.cpp   — result, res, buf

All 21 files verified with g++ -std=c++17 -fsyntax-only.

4ff1398de1 Restructure mux/ directory: component-based layout with proper build root
Move from flat mux/src/ layout to clean component hierarchy:
- mux/ is now the autoconf/automake build root (configure.ac lives here)
- mux/include/ — shared headers used by multiple components
- mux/lib/ — libmux.so (core utilities, no game state)
- mux/src/ — netmux driver only (thin networking shell)
- mux/modules/engine/ — engine.so (game logic)
- mux/modules/{comsys,mail,exp3,sqlproxy,sqlslave}/ — external modules
- mux/ganl/ — GANL networking library
- mux/sqlite/ — SQLite amalgamation (builds libsqlite3.a)
- mux/announce/ — announce tool (was mux/src/tools/)

Build changes:
- SUBDIRS ordering: ganl sqlite lib src modules announce
- libmux.so gets -Wl,-soname,libmux.so; netmux links via -L -lmux
- engine.so links libsqlite3.a and libmux.so with -Wl,--no-undefined
- RPATH uses $ORIGIN for portable .so resolution
- Install hooks use absolute paths for game/bin symlinks

Bug fixes:
- engine.so mux_Register() now passes nullptr to mux_RegisterClassObjects
  (matches all other modules; libmux already has the factory via dlsym)
- DbConvert() now calls pcache_init() before db_write, fixing a latent
  crash (free(): invalid pointer) when exporting from SQLite databases

411/411 smoke tests pass.
