* fix(#2352): tilde-expand SUMMARY.md key-files paths before deleted-file filter
compute_file_scope's "Filter deleted files" step tested the literal `~/...`
value from SUMMARY.md key-files entries with `[ -f "$file" ]`, which bash
never tilde-expands (only a literal `~` in source text expands, not one
arriving as an already-expanded variable value). Real files recorded with a
`~/...` path were silently misclassified as deleted and dropped from
REVIEW_FILES, and a phase whose every recorded file used a tilde path hit the
empty-scope skip as a false negative.
Adds a tilde-normalization loop as step 1 of post-processing (all tiers),
before the deleted-file filter, rewriting a leading `~/` to `${HOME}/...` so
downstream existence checks, the empty-scope short-circuit, and the
FILES_TO_READ/CONFIG_FILES construction all see a real, openable path.
