refactor(skills): dedup compress -> caveman-compress [v1.0.0]

skills/compress/ was a byte-identical dupe of skills/caveman-compress/
(SHA256 match across all 7 scripts/ files; SKILL.md diff was name: +
Process step 2 only; descriptions textually identical = arbitrary
harness tie-break + double-counted listing budget).

Kept caveman-compress canonical: it carries README.md (benchmarks +
caveman-toolkit branding) and SECURITY.md (Snyk false-positive writeup),
and matches the caveman-* prefix invariant.

Ported the better Process-step wording from compress
(`cd <directory_containing_this_SKILL.md>`) into caveman-compress;
the prior `cd caveman-compress` form assumed cwd was the parent dir
and broke when invoked from ~/.claude/skills/caveman-compress/.

Added version: 1.0.0 to caveman-compress frontmatter
(first versioned release; aligns with skill-versioning concept).

Removed: skills/compress/, dist/compress.skill,
~/.claude/skills/compress/ (manual prune; install.sh has no prune step
yet -- future [install-ps1] task should add --prune).

Slash-command impact: /compress gone; /caveman-compress and
/caveman:compress (toolkit-canonical) remain.

Wiki: .wiki/concepts/compress-dedup.md (rationale + rejected
alternatives), index.md + log.md updated.

Tasks: [compress-dedup] flipped active -> done in same commit
(per-task file .tasks/compress-dedup.md created with full decisions
log).
