Store Alchemist data under /switch/Alchemist (survives .packages wipe)

Point repos, pchtxts staging, contents staging, search_patterns, config,
and RELEASE metadata to /switch/Alchemist/ so OmniNX pack updates that

under .packages/Alchemist/ remain the Ultrahand entry only.

Fix truncated [*Z] section in pchtxt_cucholix.ini introduced by path edit.

The Ultrahand package lives under `/switch/.packages/Alchemist/`, while **persistent data** (repos, staging `pchtxts/` and `contents/`, `search_patterns.txt`, and `config.ini`) is stored under **`/switch/Alchemist/`** so it survives CFW pack updates that wipe `.packages`.
