CI: make versionCode step POSIX sh compatible

The runner executes workflow steps with /bin/sh (dash), which has no
here-strings: `IFS='.' read -r MAJ MIN PAT <<< "$VERSION"` failed with
"Syntax error: redirection unexpected" and aborted the Android release build.

Parse the semver with `cut` instead, drop the GNU-only `\s` from the sed
expression in favour of [[:space:]], and default any missing component to 0 so a
malformed version can never emit versionCode 0. Verified under sh:
0.0.14 -> 1014, 0.0.15 -> 1015, 0.1.0 -> 1100, 1.0.0 -> 11000 (monotonic).

  *
- * The bug these guard against: on the library route the layout used to render

- * top of it, and the library scroller only reserved 1rem — so the last row hid

+ * hidden behind the bottom nav. It was caused by rendering the bottom UI as a
+ * FIXED overlay and trying to reserve its (async-measured, initially-0) height
+ * as padding. The fix renders the bottom UI as an in-flow flex child below the
+ * scroller, so overlap is structurally impossible — no measurement, no padding.

+ * These pure functions only decide *whether* each piece shows on a route. The
