* fix(errors): one condition vocabulary, one classifier per language
A condition is named once (FsCondition) and every boundary keeps only
a table from that name to its own number: posix, wasi preview1, and
the monty guest view. CycleError gets its ELOOP seat (was EIO at every
kernel and guest boundary), the wasi wire's EXDEV is 75 per wasi-libc
(18 is EDOM there), and the cross-mount-rename-is-ENOENT decision
moves from an adapter arm into the wasi table row.
* fix(stat): one stat view per language, offset-less stamps read as UTC
mtime, dir-ness, content size and the mode bits live once per language
(utils/stat_view), delegating to the existing naive-stamp-is-UTC
parsers. Three of the four translators (node FUSE, the runtime bridge,
py wasm) read an offset-less backend stamp as local time, so python
FUSE and node FUSE disagreed by the host's UTC offset for the same
stamp; all four now answer the same epoch, pinned by tests.
* refactor(errors): move the wasi and cpython tables into their runtimes
* refactor(errors): classifier arm tables into constants modules
* fix(errors): address review on the ValueError arm and epoch-zero mtime
