feat(cli): even out the shipped tool rosters across both surfaces

The two shipped surfaces offered different tools for no recorded reason:
session checkpoints, tool-result pruning, the goal tools, and Ralph were in
`tui.cordis.yml`; `tool-todo` and web search were in `web.cordis.yml`. Neither
offered session search, a string-replacement editor, or a repeat-tool guard,
though none of the three is surface-specific.

Move the rows that are not surface-specific into `base.cordis.yml` and add
those three. Web search moves there too — the TUI decision the change that
made it a Web default deferred. Both surfaces now assemble the same 27 tools.

This adds only. No row is removed from either surface and no existing row's
configuration is edited: executors, sandbox composition, access defaults,
`tools.mode`, and the workflow tool are exactly what they were. Two rows stay
surface-specific: `tmux-context` (no terminal multiplexer in a browser) and
`session-reference` (its index has one writer owner).

Ship `dsh-mcp-client` as a dependency without a row: the plugin mounts one
server per instance and `command` is required, so a default would name a
third-party server and spawn it outside `ctx.bash` on every launch. The CLI
README carries the YAML for mounting one from a personal config.
