feat(ambient-context): trim prompt size in daily-code-metrics, test-quality-sentinel, smoke-copilot-aoai-entra

[Copilot]

Three workflows account for the largest first-request sizes in the daily ambient context audit (26k, 22k, and 16k chars respectively). This PR removes redundant inline content that duplicates shared imports or can be pre-computed deterministically outside the AI sandbox.

daily-code-metrics.md (−1,979 chars, 13.2%)

• Removed direct shared/python-dataviz.md import — already transitively included via shared/trends.md, causing the content to be injected twice
• Replaced 40-line "Python Script Structure" boilerplate code block (full imports + skeleton) with a 4-line note; the setup is already documented in python-dataviz.md
• Removed "Chart Quality Standards" and "Chart Upload and Embedding" sections — both fully covered by python-dataviz.md's existing guidance

test-quality-sentinel.md (agent body −880 chars)

Moved deterministic shell work out of the agent body into the pre-fetch steps: block (runs outside the AI sandbox, zero tokens consumed):

• Pre-extracts new Go/JS test function signatures (go-new-test-funcs.txt, js-new-test-funcs.txt) via grep on the already-fetched test diff
• Pre-checks newly added Go test files for missing //go:build tags → missing-build-tags.txt
• Simplified Step 1 and Step 2 bash blocks in the agent body to file-path references instead of repeating the shell commands
• Updated go-test-analyzer sub-agent to read missing-build-tags.txt instead of re-running git diff — removes the ${{ github.event.pull_request.base.sha }} reference from the agent body that was no longer needed

smoke-copilot-aoai-entra.md (−1,000 chars, 8.5%)

Condensed the "Tool Access Overview" section from 15 lines to 2 lines. The per-tool CLI invocation patterns (playwright, serena, safeoutputs, etc.) are restated from system-injected <mcp-clis> context; only the essential tool→CLI mapping is kept.

Pull request overview

This PR reduces first-request prompt size for several gh-aw agent workflows by removing redundant inline guidance and moving deterministic preprocessing out of the agent prompt body and into workflow steps: that run outside the AI sandbox.

Changes:

• daily-code-metrics: removes duplicated imports / boilerplate chart guidance and replaces it with pointers to the shared python-dataviz guidance (still included transitively via shared/trends.md).
• test-quality-sentinel: precomputes test-function signatures and missing Go build-tag findings during the pre-fetch step, and updates the agent body to reference the pre-fetched files.
• smoke-copilot-aoai-entra: condenses the CLI-proxy tool access explanation while keeping the key tool→invocation mapping.
