ci(coding-agent): repair current dev adapter, migration, and package-check baseline

[Yeachan-Heo]

Current dev 8eb8127e608b2d549e1c3fb9c34753ff4d484f72 is terminal red in Dev CI run 31669328497 and blocks unrelated PR #4372 after fresh-process isolation was fixed by #4428.

Exact current-dev reproductions under scripts/test-preload.ts:

• packages/coding-agent/test/sdk-adapter-dispositions.test.ts, AD-M-Q31: turn.steer_status forwarded: expected {ok:true}, receives invalid_request requiring commandId/turnId or clientRef.
• packages/coding-agent/test/session-manager-resume-readonly.test.ts, final prepared migration source-identity drift guard: strict expected error contract is not produced.
• bun --cwd=packages/coding-agent run check: current dev has a noImplicitAnyLet error at session-manager.ts receipt declaration.

Detached current-dev and PR #4372 branch results are identical. PR #4372 changes none of these source/test surfaces and must not absorb this baseline repair.

Dev CI also reports failures across shards 4/5/6 and the package check; inspect run 31669328497 as the canonical baseline owner.

Additional current-dev baseline proof from #4372: exact fresh-process CI-preload runs fail identically on PR head and detached dev 12e1df1724 for agent-session-message-pipeline, ultragoal-nudge-guard, session-directory sticky ancestry, and status-line-path. Dev run 31677847553 independently fails shard-1 job 94380290928 and multiple other shards. These are not delayed-title reachable surfaces.\n\nSigned-off-by: Yeachan-Heo yeachan-heo@gajae.dev

PR #4447 fixture-isolation review is terminal and merged as c8f60f988a0c9170ade316b3d7bd589be8091eea (reviewed exact head df4654b6402257e5ff2b62d334200b3ebfee67ff, base 12e1df1724bec0b7b1a40988cdc2a0c7dcca29ec). Exact-head CI 31682133197 is green; independent focused fresh-process verification passed all four repaired fixture surfaces and three combined rounds (126 pass, 3 platform skips, 0 fail each). Merged-dev bun run build dogfood also passed after a clean frozen-lockfile install.

This resolves only the fixture-isolation lane. #4436 remains OPEN: its full adapter/migration/package/root baseline contract requires the separate implementation owner's all-shard and exact-dev proof before closure.

Independent frozen-snapshot architecture review of the merged #4447 exact head is APPROVE with architecture/product/code all CLEAR and no blockers. Receipt hash: sha256:04d97d3e21573e367c5507f6a3f29480be48e947ecffad0e8b1f2dabc8a39f32. #4436 remains open pending the separate owner's full-contract evidence.

#4452 post-merge regression evidence

Merged PR #4452 (e4a6e45 → merge d2ac02f) did NOT fix the status-line-path failure. It only changed cached SCRATCH_ROOTS into a runtime scratchRoots() function — addressing stale root caching, not the actual root cause.

Root cause is precedence, not caching

classifyProjectDir() iterates scratch roots (including unconditional /tmp) BEFORE checking display roots. When a CI harness redirects HOME beneath the OS temp dir (HOME=/tmp/tmp.X/home), every ~/Projects path matches /tmp as scratch and gets the wrong icon + unstripped path.

Fresh-root reproduction on merged dev c06f4f5e70:

HOME=/tmp/tmp.X/home TMPDIR=/tmp/tmp.X/tmp GJC_TEST_FILE_ROOT=/tmp/tmp.X/files \
  bun test --preload ./scripts/test-preload.ts packages/coding-agent/test/status-line-path.test.ts

Result: 2/5 fail identically — scratch icon on HOME/Projects, /Projects/ not stripped.

Fix in #4456

Display roots (~/Projects, /work) now take precedence over scratch classification in classifyProjectDir(). A path inside a display root is never scratch, regardless of where HOME physically sits. Genuine OS tmp paths outside display roots remain scratch.

Also repairs current-dev package/root check lint debt (unused variables, unsafe optional chain).
