Remove github, memory, upgrade brave-search, add perplexity

- Remove github MCP server from all 10 hosts that had it (and fill-keys/docs)
- Remove memory MCP server from all 5 hosts that had it (and docs)
- Upgrade brave-search: @modelcontextprotocol/server-brave-search → @brave/brave-search-mcp-server
- Add perplexity-mcp server to all 14 hosts with PERPLEXITY_API_KEY placeholder
- Hardcode filesystem path to /spacecraft-software across all hosts
- Update fill-keys scripts: drop GITHUB_PAT, add PERPLEXITY_API_KEY
- Update server counts and docs in README.md and CLAUDE.md
- All 17 config files validate clean

+Every host template declares all ten. Two groups:
 
 **The four "real" servers** (these run in the maintainer's live configs):
 - **nixos** — `mcp-nixos` (queries nixpkgs / NixOS options). Antigravity runs the `mcp-nixos` binary directly; everywhere else it's `nix run github:utensils/mcp-nixos --` over stdio.
 - **context7** (Upstash) — HTTP, `https://mcp.context7.com/mcp`, needs a `CONTEXT7_API_KEY`. Stored inline under a header (`CONTEXT7_API_KEY` for most hosts; `Authorization: Bearer …` for VS Code, where it comes from a prompted `input`). Placeholder `YOUR_CONTEXT7_API_KEY`.
 - **microsoft-learn** — HTTP, `https://learn.microsoft.com/api/mcp`, no auth.
 - **crates** — stdio, `crates-mcp` ([crates-mcp](https://crates.io/crates/crates-mcp) via `cargo install`), queries Rust crates from crates.io and docs.rs.
 
-**The six generic servers** (came in via the merged Copilot PRs; templates-only, placeholders):
-- **github** — HTTP, `https://api.githubcopilot.com/mcp/`, `Authorization: Bearer YOUR_GITHUB_PAT` (VS Code uses built-in Copilot auth, no header).
+**The six generic servers** (templates-only, placeholders):
 - **filesystem** — stdio, `npx -y @modelcontextprotocol/server-filesystem <path>`. Hardcoded path `/spacecraft-software` across all hosts.
-- **fetch**, **memory** (disabled), **engram**, **sequential-thinking** — stdio, `npx -y @modelcontextprotocol/server-{fetch,memory,sequential-thinking}` / `engram --db ~/.gemini/engram.db mcp`, no auth.
-- **brave-search** — stdio, `npx -y @modelcontextprotocol/server-brave-search`, env `BRAVE_API_KEY=YOUR_BRAVE_API_KEY`.
+- **fetch**, **engram**, **sequential-thinking** — stdio, `npx -y @modelcontextprotocol/server-{fetch,sequential-thinking}` / `engram --db ~/.gemini/engram.db mcp`, no auth.
+- **brave-search** — stdio, `npx -y @brave/brave-search-mcp-server` ([brave-search-mcp-server](https://github.com/brave/brave-search-mcp-server)), env `BRAVE_API_KEY=YOUR_BRAVE_API_KEY`.
+- **perplexity** — stdio, `npx -y perplexity-mcp`, env `PERPLEXITY_API_KEY=YOUR_PERPLEXITY_API_KEY`.
 
 ## Conventions
 
 - Antigravity's file uses **2-space** indentation; VS Code's uses **tabs**. Preserve each file's existing style. Host directory names are **case-sensitive and canonical** (`Antigravity/`, `VSCode/`) — do not reintroduce lowercase `antigravity/` or `.vscode/` variants (a past PR did; they were consolidated).
-- Never commit a real secret — templates carry placeholders (`YOUR_CONTEXT7_API_KEY`, `YOUR_GITHUB_PAT`, `YOUR_BRAVE_API_KEY`). The filesystem server uses the hardcoded `/spacecraft-software` path. Servers needing placeholders stay inert until filled in locally.

 - Templates are the **canonical superset**; the maintainer's live machine runs the three real servers only. When changing a server, update **every** host template in its dialect (and the live config too, for the three real servers).
 
 ## Tooling
 
-`bin/fill-keys.{nu,sh,ion}` substitute the three placeholder tokens (`YOUR_CONTEXT7_API_KEY`, `YOUR_BRAVE_API_KEY`, `YOUR_GITHUB_PAT`) with values from env vars (prompting for any unset ones when interactive) and write filled copies into a **gitignored `dist/` mirror** — they never edit the tracked templates, so the no-secrets rule holds. There are three parallel ports (Nushell, POSIX/Bash/Brush, Ion) with identical behavior — **change all three together**, plus their shared host-file list (the docs and VS Code's `${input:}` field is deliberately left out). The `.sh`/`.ion` ports shell out to `sd` (literal `-s` mode); the `.nu` port uses native string ops. These are the only executables (`755`); everything else is `644` data. Shell-specific gotchas worth knowing if you edit them: Ion's `test -t` is unreliable (use `tty -s`), Ion eats `-h`/`--help`, and Ion's `test` needs the POSIX `x`-prefix guard for `--`-leading operands.
