FR: Support storing data in home directory

[ds-ok-energy-group]

Because Homunculus is supposed to be mine, I don't want to store its data in the project directory (.claude/homunculus) but in my home folder ($HOME/.claude/homunculus/). Just adding ".claude/homunculus" to my .gitignore does not suffice because I'm working with multiple git clones of the same repository in parallel.

+1 — this is actually a data-integrity bug, not just a preference.

Observed behavior: observe.sh and on_stop.sh use relative paths (.claude/homunculus/observations.jsonl and .claude/homunculus/identity.json). Claude Code's cwd varies by session — when working in a project directory, observations and identity updates go into that project's tree instead of the canonical ~/.claude/homunculus/ location.

Impact: After ~9 sessions across 4 projects, I had 988 observations scattered across 5 separate observations.jsonl files:

Location	Observations
~/.claude/homunculus/	167
~/research-lab/.claude/homunculus/	733
~/3ngram/.claude/homunculus/	136
~/quint-code/src/mcp/.claude/homunculus/	113
~/policies-and-standards/.claude/homunculus/	6

on_stop.sh also creates empty instincts/pending/ directories and updates identity.json in project dirs. The session counter gets fragmented too.

Suggested fix (2-line change):

# observe.sh line 8
-OBS_FILE=".claude/homunculus/observations.jsonl"
+OBS_FILE="$HOME/.claude/homunculus/observations.jsonl"

# on_stop.sh lines 7-8
-STATE=".claude/homunculus/identity.json"
-PENDING_DIR=".claude/homunculus/instincts/pending"
+STATE="$HOME/.claude/homunculus/identity.json"
+PENDING_DIR="$HOME/.claude/homunculus/instincts/pending"

Happy to open a PR if that would help.

I'd suggest to mimic the Claude context resolution logic.
I work in multiple subprojects but don't want to have a separate instance of homunculus in each of them. Instead, I expect to have only one in ~ or .../homunculus-enabled-projects/...
Something like this:

find_homunculus() {
  dir="$PWD"
  while [ "$dir" != "/" ]; do
    [ -d "$dir/.claude/homunculus" ] && echo "$dir/.claude/homunculus" && return
    dir="$(dirname "$dir")"
  done
  # fallback to global
  [ -d "$HOME/.claude/homunculus" ] && echo "$HOME/.claude/homunculus" && return
  echo ".claude/homunculus"  # default, will create in CWD
}

Currently I'm using symlinks in subprojects to point to my single homunculus state location.
