* agent: add a /model command to chnage current model
And remove the pick-model CLI option
* agent: add /provider to change the current provider
* agent: extract requireLlmNoArg helper
* agent: simplify provider detection
* repl: add tab completion for /model and /provider
Changes `/model` and `/provider` to accept an optional name argument
instead of prompting with a numbered list. Bare commands now print the
current selection, while Tab dynamically completes candidates. Model
lists are fetched and cached to prevent redundant network requests.
* agent: remember last selected provider and model
Persists the last selected AI provider and model in a local
`.lp-agent` file and resumes it on startup. Removes the
interactive provider picker in favor of deterministic auto-detection.
* agent: simplify requireLlm and model resolution
Changes `requireLlm` to return a boolean instead of credentials, and
cleans up the model initialization logic to use `resolved` directly.
Also removes unused user errors.

- Add `/.lp-history` to `.gitignore`.
- Make `SlashCommand.MetaCommand.Tag` private.
- Simplify loop in `tools.zig` using `while ... else`.
- Use `trimStart` instead of `trim` in `Schema.splitNameRest`.
There are two layers here. The first is that, on startup, a v8 SnapshotCreator
is created, and a snapshot-specific isolate/context is setup with our browser
environment. This contains most of what was in Env.init and a good chunk of
what was in ExecutionWorld.createContext. From this, we create a v8.StartupData
which is used for the creation of all subsequent contexts. The snapshot sits
at the application level, above the Env - it's re-used for all envs/isolates, so
this gives a nice performance boost for both 1 connection opening multiple pages
or multiple connections opening 1 page.
The second layer is that the Snapshot data can be embedded into the binary, so
that it doesn't have to be created on startup, but rather created at build-time.
This improves the startup time (though, I'm not really sure how to measure that
accurately...).
The first layer is the big win (and just works as-is without any build / usage
changes).
with snapshot
total runs 1000
total duration (ms) 7527
avg run duration (ms) 7
min run duration (ms) 5
max run duration (ms) 41
without snapshot
total runs 1000
total duration (ms) 9350
avg run duration (ms) 9
min run duration (ms) 8
max run duration (ms) 42
To embed a snapshot into the binary, we first need to create the snapshot file:
zig build -Doptimize=ReleaseFast snapshot_creator -- src/snapshot.bin
And then build using the new snapshot_path argument:
zig build -Dsnapshot_path=../../snapshot.bin -Doptimize=ReleaseFast
The paths are weird, I know...since it's embedded, it needs to be inside the
project path, hence we put it in src/snapshot.bin. And since it's embedded
relative to the embedder (src/browser/js/Snapshot.zig) the path has to be
relative to that, hence ../../snapshot.bin. I'm open to suggestions on
improving this.
