Rusty 0.1.1

Fixes and hardening after 0.1.0.

• The installer is install.sh at the top of a checkout and of a release; the files it
  installs (the unit, the MCP config, the memory-pressure drop-in) are in service/.
• Search waits at most five seconds for a query's embedding, then answers from the text
  index, so a hung Ollama no longer holds a search for two minutes.
• Two processes indexing one changed file record it once: the check and the write share a
  transaction.
• source_capture, brain_import and brain_rename run off the request's task, so a long
  one no longer holds the server up.
• Bookmarks stay inside the vault, and rusty-cli bookmarks rm removes a folder bookmark
  whose folder was deleted outside Rusty.
• import --replace through a symbolic link replaces the store where it lives, and a
  server still holding a deleted database blocks an import.
• Transcripts without a session id no longer overwrite each other in the archive.
• rusty session status names and resolves the address it probes (RUSTY_MCP_ADDR).
• A client that stops reading no longer holds up change notifications to the others.
• The sweep of outside edits leaves files written in the last three seconds to the process
  that wrote them.
• pdftotext gets thirty seconds and 8 MiB of output, and the PDF's temporary copy is
  private.

Rusty 0.1.0

The first public release.

• rusty-mcp: an MCP server with 90 tools over stdio and Streamable HTTP, resources under
  rusty://, resources/list_changed notifications, and a feed of every change in the
  store, whichever process made it (changes_since).
• The brain: a markdown vault with frontmatter, wikilinks as vault paths, a ## Timeline
  section per page, soft deletes, git history, full-text search with operators, typed
  blocks and HTML rendering, tags, properties, aliases, bookmarks, a graph, and an
  Obsidian vault import.
• Semantic search with a local Ollama model, or OpenAI only when set and keyed.
• The brain loop (brain_ask, brain_decide, brain_follow_up, brain_due) and two
  optional Claude Code hooks (rusty-cli hooks install).
• To-do lists, memories, notes, settings (credentials masked on read), and secrets behind
  a PIN.
• A skills store with staging, a safety scan, and *.sh scripts run as rusty <name>.
• Sources: web pages, PDFs and files captured as pages and marked untrusted.
• rusty-cli export and import: a whole store in one zip, secrets only on request.
• A conversation archive: rusty-cli ingest-conversation keeps Claude Code transcripts as
  searchable text and brain pages; search_conversations searches it.
• rusty-cli for the terminal (settings included), rusty for the service and store
  scripts, a systemd user service and an installer that builds from source or installs a
  release's binaries.
• References generated from or checked against the code: docs/tools.md, docs/cli.md,
  docs/configuration.md.
