G-098 increment 2: tklib installed via its own installer (batch, suite shell); tooltip smoke

Installer behaviour checked first per user caveat: module exclusions,
app-script generation, doc options, and the aggregating top-level
pkgIndex.tcl (gen_main_index) - not a straight copy; critcl DSL stubbed to
no-ops (pure-tcl). Driver runs it with the suite-built tclsh in batch mode,
packages only, landing out/lib/tklib0.9. Smoke: package require Tk +
tooltip -> 2.0.4 in the suite shell.

+
+- Installer behaviour checked (per the user's caveat) before use: NOT a straight copy
+  - module exclusion list (unless +excluded), app-script generation, optional
+  nroff/html doc install, and generation of the aggregating top-level pkgIndex.tcl
+  (gen_main_index sources each module's index - required for package resolution since
+  module indexes sit two levels below auto_path). critcl DSL procs are stubbed to
+  no-ops (pure-tcl confirmed). Batch surface: -no-gui -no-wait with
+  -pkgs/-apps/-html/-nroff/-examples toggles and *-path overrides; default paths
+  derive from the RUNNING tclsh.
+- Driver step: run installer.tcl with the SUITE-BUILT shell, batch, packages only
+  (-no-gui -no-wait -pkgs -no-apps -no-html -no-nroff -no-examples) - defaults land
+  it at out/lib/tklib0.9 with the generated main pkgIndex. Idempotent (skipped when
+  a tklib* install exists).
+- SMOKE PASS: in the suite shell, package require Tk + package require tooltip ->
+  tooltip 2.0.4 (a Tk-dependent tklib package resolving through the aggregate index).
