Standardize justfile targets

Description

The five developer commands now mean the same thing in every Calysto repo: install, test, cover, typing, and lint.

Two things were confusing before. lint ran a hand-picked subset of pre-commit hooks while a separate pre-commit recipe ran all of them, so neither name described what it did. Recipes also did not control their own environment, so running one target could leave dependencies in a state the next target did not expect. Each recipe now syncs the exact dependency groups it needs, which makes any order of commands safe.

Changes

• Renamed the run-all-hooks recipe from pre-commit to lint
• Added lint-all for hooks that only run at the manual stage, such as markdown-link-check
• Every recipe syncs the dependency groups it needs before doing its work
• Updated the contributing guide to match

Backwards-incompatible changes

just pre-commit no longer exists. Use just lint, or just lint-all to include the manual-stage hooks.

Testing

• just lint passes
• just typing passes with no issues in 13 source files
• just test passes, 174 tests
• Ran just test followed by just lint to confirm the second command re-syncs its group instead of failing on a pruned environment
