fix(workflows): use canonical doctor package in managed CI

[artiphishle]

Goal

Update the Devtools-managed CI workflow so repository validation uses the current canonical Doctor entrypoint instead of the obsolete ankh doctor validate . command path.

Discovered while bootstrapping ankhorage/game for ankhorage/palabichos#29.

Evidence

The current managed workflow source still renders:

bunx @ankhorage/ankh doctor validate .

Current @ankhorage/ankh returns:

Unknown Ankh command: doctor validate .
Try:
  ankh --help

Meanwhile ankhorage/ankh's own current CI already validates through the dedicated package:

BUN_INSTALL_CACHE_DIR="${RUNNER_TEMP}/doctor-cache" bunx @ankhorage/doctor@0.10.14 validate .

So newly synced repositories can receive a CI command that no longer works with the current CLI routing.

Required skills

Before implementation:

• read AGENTS.md;
• inspect .agents/skills/;
• load .agents/skills/ankhorage-coding-rules/SKILL.md;
• load .agents/skills/ankhorage-project-structure/SKILL.md when managed workflow ownership/structure is affected;
• load any repository-local workflow/release skill that applies.

Scope

• Update the canonical managed CI workflow source to call the supported @ankhorage/doctor entrypoint.
• Source the Doctor version from the canonical Devtools/Ankh policy rather than scattering an unrelated literal where an owned constant already exists or should exist.
• Update workflow rendering/tests that currently assert bunx @ankhorage/ankh doctor validate ..
• Update generated/managed documentation sources that describe the obsolete command.
• Ensure repository sync distributes the corrected workflow.
• Do not add compatibility routing back into ankh solely to preserve the obsolete CI command.

Acceptance criteria

• Freshly synced CI validates a canonical Ankhorage repository successfully using the supported Doctor package.
• Workflow tests assert the new canonical command.
• Existing managed CI behavior (build/lint/format/Knip/tests/typecheck/changeset status) remains unchanged.
• Build, check-types, lint, Knip, changeset and format pass.

Delivery
