#913: enforce --pin on link and jeo:assemble

[bibonix]

@yegor256 this PR fixes #913.

Problem

In src/eoc.js, every build command except link and jeo:assemble calls pin(program.opts()) as the first statement of its action handler — that's the helper that compares --pin=X.Y.Z against the running eoc version and exits 1 with Version mismatch: ... on a mismatch. Because link and jeo:assemble were missing that call, a project pinned to a specific eoc version would silently bypass the version check when those two commands were invoked.

Changes

Two small commits:

1. #913: add failing tests for --pin on link and jeo:assemble — adds two regression tests in test/test_eoc.js that invoke eoc --pin=29.9.4 --alone link and eoc --pin=29.9.4 jeo:assemble, asserting the standard Version mismatch: you are running eoc <X.Y.Z>, but --pin option requires 29.9.4 error is raised. Without the fix both tests fail: link --alone runs to completion silently, and jeo:assemble fails downstream inside Maven for an unrelated reason.

2. #913: enforce --pin in link and jeo:assemble action handlers — adds pin(program.opts()) as the first statement of each handler, mirroring the pattern used by compile, transpile, clean, register, parse, assemble, lint, resolve, dataize, test, print, docs, jeo:disassemble, latex, normalize, and fmt.

Net diff: +2 lines in src/eoc.js, +18 lines in test/test_eoc.js.

Verification

• npx eslint — clean.
• npx mocha test/test_eoc.js — all 8 tests pass (6 pre-existing + 2 new).
• All 16 CI checks green on this PR (grunt build × 3 OSes, itest × 3 OSes, eslint, typos, pdd, xcop, copyrights, reuse, yamllint, markdown-lint, shellcheck, actionlint).

Ready for merge.

@bibonix Hey! Just a heads up - the branch name fix-pin-link-jeo-assemble doesn't follow our naming convention, so that's -6 points according to our policy. It's really not a good idea to name branches this way. Next time, just use the ticket number - so for this one, 920 would've been perfect! Your running score is +70, so you're still doing great overall. Don't forget to check your Zerocracy account too! 🚀
