shoney.arickathil 734ddfe2d6 feat: installable toolchain — version, wovm self-locate, dist tarball
Close the 3 gaps between "builds in the repo" and "installs from a tarball
like Go", so writeonce can ship to other developers.

- VERSION file at repo root single-sources the toolchain version (0.1.0).
- `woc version` -> "writeonce 0.1.0 linux/amd64"; `wovm --version` -> "wovm
  0.1.0" (stamped by the Makefile from VERSION; --version handled only in the
  plain-wovm path so a built app never shadows its own `version` arg).
- wo.toml `[runtime] wo = ">= X.Y"` is now ENFORCED: woc refuses a project
  requiring a newer toolchain than itself (>= and bare version parsed;
  unknown operators accepted forward-compatibly). Was parsed-and-ignored.
- woc self-locates wovm: --runtime > [build] runtime > $WO_RUNTIME > a `wovm`
  beside the woc binary (Sys.executable_name) > runtime/wovm rel CWD. An
  installed woc in <prefix>/bin finds its sibling wovm from any cwd.
- `just dist` (scripts/mkdist.sh) packages writeonce-<ver>-linux-amd64.tar.gz,
  Go-shaped (archive root writeonce/, bin/{woc,wovm}, README, VERSION), with a
  drift guard asserting VERSION == woc == wovm. dist/ gitignored.
- `just install-accept` (scripts/install-accept.sh) is the gate: extract, PATH,
  version, build+run a project from an unrelated cwd, constraint refusal — 6/0.

Verified: install-accept 6/0; woc-test 565/0; wovm suites + cli_smoke;
log-watcher 7/0. Linux-amd64 only (a cross matrix is future work).
