Rename task CLI from ask to do

- Move cmd/ask to cmd/do; mage BuildDo builds binary named do
- Update askcli help text, errors, Fish completion (complete -c do, __do_*)
- Task alias cache path: XDG cache hexai/do/task-aliases-v2.json
- Refresh README and docs; go install path cmd/do@latest
- Remove accidentally tracked cmd/ask build artifact; ignore cmd/do/do and cmd/do/ask

 # Fish Completion
 
-The `ask` task-management CLI embeds its Fish completion script in the binary and prints it with `ask fish`.
+The `do` task-management CLI embeds its Fish completion script in the binary and prints it with `do fish`.
 
-It completes the top-level `ask` subcommands and the nested `ask dep` operations.
-It also completes task selectors for UUID-taking commands by reading pending tasks through `ask complete-uuids`, which uses the local alias cache for stable short IDs.

 Fish suggests each task's alias ID first and also keeps the raw UUID available as a fallback selector.
-Selector suggestions stop once a command has consumed its selector argument, and `ask dep add` / `ask dep rm` suggest selectors for both task positions.
-When typing `ask add depends:...`, Fish also completes the comma-separated dependency selector list inside the `depends:` modifier.

 The script preserves the global `--json` flag.
 
 Load it into the current Fish session:
 
 ```sh
-ask fish | source
+do fish | source
 ```
 
 If you installed with `mage install` and `~/go/bin` is not on your `PATH` yet, use:
 
 ```sh
-~/go/bin/ask fish | source
+~/go/bin/do fish | source
 ```
 
 To enable it automatically for new Fish sessions, add this to your Fish config or a file in `~/.config/fish/conf.d/`:
 
 ```fish
-set -l ask_bin ~/go/bin/ask
+set -l do_bin ~/go/bin/do
 
-if test -x $ask_bin
-    $ask_bin fish | source
+if test -x $do_bin
+    $do_bin fish | source
 end
 ```
 
-No external `ask.fish` file is required.
+No external `do.fish` file is required.
