Remove obsolete repository coupling and stabilize CI installs

[bigboateng]

Change contract

When: Contributors run repository checks or read Pitot's CI reports and SDK documentation.
Before: Historical import metadata and layout fallbacks remained, tests could select an adjacent checkout, and reports attributed verification to a retired source. DeepSeek's top-level version pin also allowed new transitive releases to change its installation between capture and verification.
After: Tests and reports describe this repository. The unused import snapshot is removed, SDK links resolve correctly, and DeepSeek's CI installation uses a checked-in dependency graph. Rejected captures name the differing fields; Qwen replay failures include bounded shell-result diagnostics.

Boundaries preserved

• Keep active CI authentication, report markers and aggregation, runtime behavior, licenses and third-party attribution.
• Keep complete installed-tree checks and all supported agent/platform coverage. Both dependency manifests are included in the capture producer inventory.
• Keep strict fixture equality and allow/deny trajectory checks. Diagnostics omit raw commands, paths and arbitrary error content.
• Change only DeepSeek's CI installation; retain the same agent versions and other installers.

Evidence

Scenario or check	Expected result	Observed result
Obsolete metadata, repository-local test roots and SDK links	Remove stale coupling	Independent source review passed
DeepSeek dependency resolution	Fixed graph with package integrity and optional platform dependencies	Lock retains 609 package entries and cross-platform optional packages; installer regression tests passed
Installer and replay diagnostics	Preserve rejection gates and redact values	13 installer and 54 replay-driver tests passed
Formatting, static and full maintenance checks	Pass	Passed; 232 maintenance tests, 3 platform-specific skips
Changed producer inventory with old capture	Reject stale evidence	Rejected as expected
Fresh native capture	Authenticate all 33 cells and 47 producer bindings	Run 38422394339 passed; independent re-download matched all artifacts
Final Windows, macOS and Linux PR CI	All checks and current report pass	49 checks passed at 8dad60572851; current report has 33 passing agent cells and 3 passing runtime cells

Failure and recovery

DeepSeek's dependency ranges admitted a transitive package published between a successful capture and later verification. A fresh diagnostic capture differed only in the complete installation-tree digest. The lock prevents that dependency resolution from changing on each install; the full-tree check still detects other differences. Revert source and its accompanying capture record together if needed.

Remaining limits

The original failed installation record and Qwen shell status were not retained, so their exact contents cannot be reconstructed. Qwen passed a later unchanged-source diagnostic run; the added diagnostics do not claim to fix an identified Qwen runtime defect. Fresh native capture and final PR checks passed. Two macOS jobs initially received no hosted runner; a same-commit failed-job retry passed. Git history and external repository settings are outside this cleanup; the broader README and reference-documentation work follows separately.
