fix(plugin): slug regex + script path resolution for npm install (v0.8.2)

Two critical bugs discovered during real-user flow simulation — both
block adopt/doctor from working in any non-dev install layout.

**Bug 1 — slug regex** (adopt.js): memoryDir used `cwd.replace(/\//g, '-')`
which only handled forward slashes. Claude Code's actual slug convention
is every non-alphanumeric-non-hyphen char → `-`. For the common dev path
`/mnt/data_ssd/...` this caused the underscore to be preserved, producing
`-mnt-data_ssd-...` instead of the actual `-mnt-data-ssd-...` dir name.
Result: adopt always reported "Memory dir not found" for the user's own
project. Test coverage gap: existing tests used underscore-free paths.

Fix: cwd.replace(/[^a-zA-Z0-9-]/g, '-'). Added 1 test covering
underscores, dots (double-dash from `/.`), case preservation, trailing
version numbers. All 77 tests pass (was 76).

**Bug 2 — script path resolution** (main.rs): run_node_script looked
only at exe_dir/../../ and exe_dir/../ for claude-plugin/scripts/. In
npm install layout, the binary lives in
node_modules/@sdsrs/code-graph-<plat>/ but claude-plugin/ is in the
sibling main pkg node_modules/@sdsrs/code-graph/ — unreachable via
relative-from-exe. Same issue for auto-update-cache binaries at
~/.cache/code-graph/bin/. Affected adopt/unadopt (new) AND the
pre-existing doctor subcommand.

Fix: first consult $_FIND_BINARY_ROOT env var (set by bin/cli.js npm
wrapper to main pkg root) before relative-from-exe. Dev mode still
works via candidate 2 (exe_dir/../../). Error message now lists all
candidates searched so users can self-diagnose install issues.

E2E verification:
- Direct binary from repo root: adopt succeeds for actual user cwd
- cli.js wrapper + auto-update-cache binary: adopt.js located via
  $_FIND_BINARY_ROOT, slug correct, flow reaches memoryDir check
- Quiet mode MCP instructions: 338 chars (unchanged from v0.8.1)
- session-init.js quiet: mapInjected=false (unchanged)
