Log Message:
SyncTERM: File.readLine + File.writeLine

readLine() reads from the current offset to the first LF (0x0A) or
EOF and returns the bytes with any trailing LF removed. Offset
advances past the LF on a hit, or to EOF if none found. Returns
null when already at EOF so a typical loop terminates cleanly; a
blank line is the empty string, distinct from EOF.

writeLine(s) writes the bytes of s at the current offset, then
appends an LF. Offset advances past the LF. No special-casing if
s already ends in LF — writeBytes() is the way to opt out of the
trailing-LF behavior.

Implementation chunks reads through a 512-byte buffer with
geometric growth on long lines, so a 100GB file with short lines
doesn't allocate the whole remainder up front.

Log Message:
SyncTERM: File.sha1 / File.md5 + missing docs and tests

File.sha1 and File.md5 hash the file's full content via xpmap and
the existing src/hash sha1.c / md5.c. Zero-length files are
special-cased to an empty buffer because xpmap rejects 0-sized
maps. Returned as raw digest bytes (Wren strings are byte-safe)
so they compare directly against SFTPEntry.hash from the
sha1s@syncterm.net / md5s@syncterm.net SFTP extensions; format hex
yourself if you need it for display.

Also catches Wren.adoc + wrentest.wren up to recent work that
shipped without docs / tests:

- New Wren.adoc sections for Platform, Timer (+ TimerElapsed), SFTP
(+ FileFlag, SFTPEntry, SFTPStat, SFTPHandle, SFTPError, and the
shared async-op pattern used by Timer / SFTP / Input.nextEvent).
File doc gets the sha1 / md5 row added.

- wrentest.wren coverage:
Platform.name returns non-empty String.
File.sha1 / File.md5 of an empty file (exercises the
zero-length code path) and of "hello" (exercises xpmap).
Timer.trigger(ms=0) parks a fiber, the doterm sweep marks it
past-due, the drain resumes with a TimerElapsed.
