be820d0337 tcl: Phase 5 channel I/O — open/read/gets/puts/seek/tell/eof/fconfigure
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 2m0s
Details 
11 new SX primitives in sx_primitives.ml wrapping Unix.openfile/read/write/
lseek/set_nonblock: channel-open/close/read/read-line/write/flush/seek/tell/
eof?/blocking?/set-blocking!.

Tcl runtime now uses real channel ops:
- open ?-mode? returns "fileN" handle (modes r/w/a/r+/w+/a+)
- close/read/gets/puts/seek/tell/eof/flush wired through
- new fconfigure command supports -blocking 0|1
- puts dispatches to channel-write when first arg starts with "file"
- gets command registration fixed (was pointing to old stub)

eof-returns-1 coro test updated to match real Tcl semantics (eof flips
only after a read hits EOF).

Test runner timeout bumped 180s→1200s (post-merge JIT is slow).

+7 idiom tests covering write+read, gets-loop, seek/tell, eof-after-read,
append mode, seek-to-end, fconfigure-blocking. 349/349 green.

2c61be39de tcl: Phase 6 coroutines + clock/file stubs + idiom corpus (+40 tests, 329 total)
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Has been cancelled
Details 
- Coroutines (generator-style): coroutine/yield/yieldto commands; eager yield
  collection during body execution, pop-on-call dispatch via registered command
  closures; coro-yields + coroutines threaded through tcl-call-proc
- info exists varname (plus hostname/script/tclversion stubs)
- clock seconds/milliseconds/format/scan stubs
- File I/O stubs: open/close/read/eof/seek/tell/flush + file subcommands
- format command: full %-specifier parsing with flags, width, zero-pad, left-align
- Fixed dict set/unset/incr/append/update to use tcl-var-get (upvar alias aware)
- Fixed lappend and append to use tcl-var-get for reading (upvar alias aware)
- 20 coroutine tests (coro.sx) + 20 idiom corpus tests (idioms.sx)
- event-loop.tcl program: cooperative scheduler demo using coroutines
- Note: coroutines eagerly collect yields (generator-style, not true suspension)
