ci: align pre-commit hooks and adopt org-wide GitHub defaults

Adopt the shared pre-commit baseline: conventional-commit message
validation (commit-msg stage) and the centralized add-license hook from
the org .github repository (v1.0.0 - excludes .github/ templates and
never rewrites LICENSE files). Run pre-commit CI only on files modified
by the PR, and add the caller stub for the org-wide conventional-pr
reusable workflow (PR title validation + type labeling).

PR and issue templates are no longer stored per repository: they are
inherited from the org-wide defaults in triton-inference-server/.github
(issues route to the server repository).
