chore: align local ruff with CI's dependency window

[kirangadhave]

Problem

make py-check runs uv run ruff check --fix, which re-resolves ruff rather than using a frozen lock (uv.lock is gitignored). Locally there was no upper bound, so it floated to whatever ruff uv resolved at setup time (observed 0.15.13 / 0.15.14 / 0.15.15 across environments). CI's lint job (test_check in test_be.yaml) runs the same command but with UV_EXCLUDE_NEWER: "7 days", so CI resolves the latest ruff aged ≥7 days. The newer local ruff ships detections/fixes (TC002/TC003 import moves, unused-import removals) that CI's windowed version lacks, so local checks rewrote files CI considered clean.

Fix

Make local resolution reproduce CI's window at setup time:

• pyproject.toml: add [tool.uv] exclude-newer = "7 days", mirroring CI's UV_EXCLUDE_NEWER. Local uv run/uv lock now resolve the same ruff (and other deps) CI would resolve when you set up. This is point-in-time: a fresh setup matches CI; a stale checkout matches once re-locked.
• .pre-commit-config.yaml: pin ruff-pre-commit to the version that window currently resolves (v0.15.14), since pre-commit.ci installs from the tag and isn't governed by the window. Renovate (minimumReleaseAge: 7 days) keeps the tag tracking.
• Commit the autofixes the windowed ruff produces: unused-import removals and type-only imports relocated into TYPE_CHECKING.

No version is hard-pinned; the floor stays ruff>=0.15.9 and the window controls the upper bound.

Verification

• uv run ruff --version -> 0.15.14 (== pre-commit rev == CI's windowed resolution)
• uv run ruff check . && uv run ruff format --check . -> clean
• uvx ruff@0.15.14 check . -> All checks passed
• uvx pre-commit run ruff-check/ruff-format --all-files -> Passed
• make py-check -> lint, format, typecheck (713 files), lock all pass
• All modified modules import cleanly; tests/_runtime/test_manage_script_metadata.py -> 14 passed

didn't realize the ruff version was released recently.
