Removed `xrpcclient.HandleXrpcErr()` call as appview always expect
knotmirror with compatible API.

These experimental xrpc methods use at-uri instead of did/name format to
reference the repository.

`sh.tangled.pipeline` events are now completely generated & streamed
from spindle

Signed-off-by: Seongmin Lee <git@boltless.me>

spindle will emit `sh.tangled.pipeline` event on:
- `sh.tangled.git.refUpdate` events from knot stream
- live create/update events of `sh.tangled.repo.pull` records

Spindle will sync git repo when new repo is registered

Spindle will listen to `sh.tangled.git.refUpdate` event from knot
stream and sync its local git repo instead. Spindle's git repo will
sparse-checkout only `/.tangled/workflows` directory.

Spindle now requires git version >=2.49 for `--revision` flag in `git
clone` command.

This single persistent directory can be used for storing general spindle
data like db, motd file and upcoming sparse-clone git repos.

db path will be `${DATA_DIR}/spindle.db`

spindle-tap will collect/stream record events from:
- users dynamically added by spindle (spindle members | collaborators of
repos using spindle)
- any users with `sh.tangled.repo.pull` collection

It might be bit inefficient considering it will also stream repo
creation events from PR authors due to second rule, but at least we now
have backfill logic and Sync 1.1 based syncing.

This inefficiency can be fixed later by modifying upstream tap cli or
embedding tap into spindle.

```

This new db migration won't migrate existing records in repos table.
Instead, it will simply rename the legacy table to `repos_old` and
create a new one with same name.

repo backfill will be done with tap

Add sandboxed atmosphere environment for local testing. This new vm
contains everything required to run local test appview including PLC,
PDS, Jetstream (listening to single PDS), knot and spindle.

I'm using my custom `tngl.boltless.dev` domain which resolves to
`127.0.0.1` without any proxy.

PLC: plc.tngl.boltless.dev
PDS: pds.tngl.boltless.dev
Relay: relay.tngl.boltless.dev
Jetstream: jetstream.tngl.boltless.dev
Knot: knot.tngl.boltless.dev
Spindle: spindle.tngl.boltless.dev

TLS is supported with caddy service running inside the vm.

note: `pds.env` file here is hard copy to be used for contrib/scripts.
note: upgraded pds package in order to set email settings
