feat(marketplace): add orientation plugin (#376)

orientation reconstructs the real history of code (goal, shipped vs in-flight,
coupled files) from Codex, Claude Code, and Eigen transcripts and surfaces it
via the get-oriented skill, so agents stop guessing the story of code they
didn't write this session.

Pinned to v0.2.0 (commit 417d496320b8330013efc0c7fcb51792453376a6, the
dereferenced tag commit) per the immutable-pin contract; mirrored in
scripts/plugins.txt. pin-marketplace.js --dry-run independently resolves the
same commit, and the marketplace contract + full suite pass.
