A fallible function returns a `result` value, built with ok(payload) on success
or err(message) on failure. The caller recovers a value with `try EXPR else {
… }`: on ok the whole expression is the payload; on err the else block runs —
with the failure message bound to `error` — and its trailing expression supplies
the fallback. It is a plain branch on the result's tag: no exceptions, no hidden
control flow, nothing unwinds. is_ok(r) / is_err(r) classify without unwrapping.
Payloads are any i32-width scalar (int/fixed/bool/entity). The feature is
additive and only kicks in when ok/err/try are used, so untouched programs
compile byte-identically (verified) and the C-free bootstrap fixpoint holds.
Complements panic/assert from #8 (the unrecoverable half). The optional
top-level frame `recover` stays deferred (needs a frame-abort mechanism); the
full tagged-union/any generalization is tracked in #1.
Adds the `try` keyword and ok/err/is_ok/is_err builtins across the compiler,
the vocabulary header, JetBrains + TextMate/VSCode grammars, the docs inventory
and pages, examples/library/recover.ludic, and a regression case.

Changesets
A changeset is one small Markdown file describing a single user-facing change,
dropped in this directory. x release consumes every changeset here into a new
CHANGELOG.md section, bumps VERSION, and deletes the consumed files.
Format
bump: minor
type: feat
One or more lines describing the change, in the past-agnostic imperative used in
the changelog. Markdown is fine.
bump:—major,minor, orpatch(SemVer). The release version is bumped by the highest level among the pending changesets (unlessx release <level>overrides it).type:— the Conventional Commit type (feat,fix,perf,docs, …); it becomes the bold prefix of the changelog bullet.
Adding one
Create a file with a short, unique name, e.g. changes/regex-namespace.md. Any
filename works except this README.md, which the release step always skips.
