Log Message:
SyncTERM: extract syncterm Wren module to scripts/syncterm.wren

The 740-line foreign-class-declaration string literal in wren_host.c
moves to scripts/syncterm.wren as plain Wren source. Now editable
with syntax highlighting, comments stay readable, no escape-quote
gymnastics. The build embeds it via the existing scripts/*.wren
glob alongside connected.wren and console.wren.

Load order: wren_host_init() now resolves "syncterm" first (preferring
a user override at scripts/syncterm.wren on disk, falling back to the
embedded copy), captures the Cell/Cells/KeyEvent/MouseEvent class
handles, then walks the rest of EMBEDDED_SCRIPTS[] and the user
script dir Ä both passes skip the syncterm entry to avoid double-load.

Bonus fix shaken out by the move: parse() in RE1 unconditionally
prepended `.*?` to every pattern for match-anywhere semantics, which
defeated the streaming dispatcher's IMPOSSIBLE-shift trim. Add parse_unanchored() that returns the user's pattern wrapped only in
the implicit group-0 capture; Hook.onMatch uses it. parse() keeps
its original behavior for any future buffer-shaped caller.

scripts/runtests.wren needed an explicit `import "syncterm" for Hook`
since it loads as its own "runtests" module (not embedded, not in
the syncterm scope).
