shell: fish functions -> ~/.local/bin executables + bash/zsh ports; manage ~/.agents

- 16 cross-shell utilities converted to sh/bash chezmoi executables:
  ai c2p cp-appid extract_agents fab gdc gh-sonr-org-migrate ghg-clone
  ghn gho git-summary launch_omp_livediff_overlay lc-elir mdcp mdp pj
  (ghg-clone not named ghg: unrelated cargo binary owns that name)
- cwd/history helpers stay per-shell: yy c cd clip-last + ghg/ghn/gho
  cd-wrappers in bash/functions/ and zsh/functions/, loaded by rc files
- fish keeps only shell-state functions; converted ones now hit PATH
- cp-appid ignore gating moved to .local/bin path
- dot_agents/skills: 82 skills materialized from dotstate storage so
  dot_claude skill symlinks resolve on fresh bootstrap; dotstate
  profile/symlinks.json released .agents/skills .bashrc .zshrc

+# Changelog

+## 2026-01-13
+
+### Added
+
+**Phrases (references/phrases.md)**
+- Throat-clearing: "Here's what I find interesting", "Here's the problem though"
+- Performative emphasis: "creeps in", "I promise", "They exist, I promise"
+- Telling instead of showing: "This is genuinely hard", "This is what leadership actually looks like"
+
+**Structures (references/structures.md)**
+- Binary contrasts: "Not X. But Y.", "It's not this. It's that.", "stops being X and starts being Y"
+- Rhythm patterns: staccato fragmentation, dashes for dramatic pause, hedging as reassurance
+- Word patterns: absolute words (always, never, everyone, etc.), AI-overused intensifiers (deeply, truly, fundamentally, inherently, simply, literally, inevitably)
+
