perf: drop the precompile workload and run the package interpreted - #314

The workload from #309 cached about 4,400 specializations, most of them Base methods, and verifying their backedges made DocStringExtensions take 33 ms to load where 0.10.0 took 4 ms. PrecompileTools also pulled in Preferences, TOML and Dates. Each dependent package paid that on every load, while the gain went only to sessions that render a docstring. Without the workload the first render took 1 s. From Julia 1.6 the module now sets `compile=min optimize=0`, keeping inference on so the type stability checks still hold. Interpreted code costs nothing to compile, but a closure passed to a Base function such as `map`, `filter`, `sort!` or a comprehension compiles a new specialization of that function. So the render path uses loops, and `methodgroups` groups by hand and sorts with `insertion_sort!`, replacing `groupby` and two `sort!` calls. The first render now takes about 0.19 s and loading about 4 ms. Closes #313
…sures `optimize=0` changed neither load time, first render nor the CImGui.jl docs build, so the module sets `compile=min` alone. A trace of the first render across every abbreviation still showed Base compiling for DSE: - `ComposedFunction` calls in `INSTANCES` and `SUBTYPES` - closures on the signature and name-list paths, such as `collapse_defaults` and `print_name_list` - `format(::ModuleImports)` itself, which Julia compiles because it holds a `ccall` Those are loops now, and each `ccall` sits in a function of its own. The first render of every abbreviation drops from 309 ms to 170 ms on nightly. `AGENTS.md` records the rule so new code keeps to it.

Drop the #309 precompile workload, which slowed loading of every dependent package, and run the package interpreted from Julia 1.6. Closes #313.
