chore(release): prepare for 1.151.5

This fixes HTML display of truncated (long) sent messages ("Show full message" in UIs). Before,
incorrect HTML was stored (with missing line breaks etc.) for them. Now stored plaintext is
formatted to HTML upon calling `MsgId::get_html()` and this results in the same HTML as on a
receiver side.

-### Coding conventions
-
-We format the code using `rustfmt`. Run `cargo fmt` prior to committing the code.
-Run `scripts/clippy.sh` to check the code for common mistakes with [Clippy].
-
-Commit messages follow the [Conventional Commits] notation.
-We use [git-cliff] to generate the changelog from commit messages before the release.
-
-With **`git cliff --unreleased`**, you can check how the changelog entry for your commit will look.
-
-The following prefix types are used:
-- `feat`: Features, e.g. "feat: Pause IO for BackupProvider". If you are unsure what's the category of your commit, you can often just use `feat`.
-- `fix`: Bug fixes, e.g. "fix: delete `smtp` rows when message sending is cancelled"
-- `api`: API changes, e.g. "api(rust): add `get_msg_read_receipts(context, msg_id)`"

-Release preparation commits are marked as "chore(release): prepare for vX.Y.Z".
-
-If you intend to squash merge the PR from the web interface,
-make sure the PR title follows the conventional commits notation
-as it will end up being a commit title.
-Otherwise make sure each commit title follows the conventional commit notation.
-
-#### Breaking Changes
-
-Use a `!` to mark breaking changes, e.g. "api!: Remove `dc_chat_can_send`".
-
-Alternatively, breaking changes can go into the commit description, e.g.:
-
-```
-fix: Fix race condition and db corruption when a message was received during backup
-
-BREAKING CHANGE: You have to call `dc_stop_io()`/`dc_start_io()` before/after `dc_imex(DC_IMEX_EXPORT_BACKUP)`
-```
-
-#### Multiple Changes in one PR
-
-If you have multiple changes in one PR, create multiple conventional commits, and then do a rebase merge. Otherwise, you should usually do a squash merge.

-
-### Errors
-
-Delta Chat core mostly uses [`anyhow`](https://docs.rs/anyhow/) errors.
-When using [`Context`](https://docs.rs/anyhow/latest/anyhow/trait.Context.html),
-capitalize it but do not add a full stop as the contexts will be separated by `:`.
-For example:
-```
-.with_context(|| format!("Unable to trash message {msg_id}"))
-```
-
-All errors should be handled in one of these ways:
-- With `if let Err() =` (incl. logging them into `warn!()`/`err!()`).
-- With `.log_err().ok()`.
-- Bubbled up with `?`.
-
-`backtrace` feature is enabled for `anyhow` crate
-and `debug = 1` option is set in the test profile.
-This allows to run `RUST_BACKTRACE=1 cargo test`
-and get a backtrace with line numbers in resultified tests
-which return `anyhow::Result`.
-
-### Logging
-
-For logging, use `info!`, `warn!` and `error!` macros.
-Log messages should be capitalized and have a full stop in the end. For example:
-```
-info!(context, "Ignoring addition of {added_addr:?} to {chat_id}.");
-```
-
-Format anyhow errors with `{:#}` to print all the contexts like this:
-```
-error!(context, "Failed to set selfavatar timestamp: {err:#}.");
-```
-
-### Reviewing
-
-Once a PR has an approval and passes CI, it can be merged.
-
-PRs from a branch created in the main repository, i.e. authored by those who have write access, are merged by their authors.
-This is to ensure that PRs are merged as intended by the author,
-e.g. as a squash merge, by rebasing from the web interface or manually from the command line.
-
-If you do not have access to the repository and created a PR from a fork,
-ask the maintainers to merge the PR and say how it should be merged.

+# Coding conventions
+
+We format the code using `rustfmt`. Run `cargo fmt` prior to committing the code.
+Run `scripts/clippy.sh` to check the code for common mistakes with [Clippy].
+
+[Clippy]: https://doc.rust-lang.org/clippy/
+
+## SQL
+
+Multi-line SQL statements should be formatted using string literals,
+for example
+```
+    sql.execute(
+        "CREATE TABLE messages (
+id INTEGER PRIMARY KEY AUTOINCREMENT,
+text TEXT DEFAULT '' NOT NULL -- message text
+) STRICT",
+    )
+    .await?;
+```
+
+Do not use macros like [`concat!`](https://doc.rust-lang.org/std/macro.concat.html)
+or [`indoc!](https://docs.rs/indoc).
+Do not escape newlines like this:
+```
+    sql.execute(
+        "CREATE TABLE messages ( \
+id INTEGER PRIMARY KEY AUTOINCREMENT, \
+text TEXT DEFAULT '' NOT NULL \
+) STRICT",
+    )
+    .await?;
+```
+Escaping newlines
+is prone to errors like this if space before backslash is missing:
+```
+"SELECT foo\
+ FROM bar"
+```
+Literal above results in `SELECT fooFROM bar` string.
+This style also does not allow using `--` comments.
+
+---
+
+Declare new SQL tables with [`STRICT`](https://sqlite.org/stricttables.html) keyword
+to make SQLite check column types.
+
+Declare primary keys with [`AUTOINCREMENT`](https://www.sqlite.org/autoinc.html) keyword.
+This avoids reuse of the row IDs and can avoid dangerous bugs
+like forwarding wrong message because the message was deleted
+and another message took its row ID.
+
+Declare all new columns as `NOT NULL`
+and set the `DEFAULT` value if it is optional so the column can be skipped in `INSERT` statements.
+Dealing with `NULL` values both in SQL and in Rust is tricky and we try to avoid it.
+If column is already declared without `NOT NULL`, use `IFNULL` function to provide default value when selecting it.
+Use `HAVING COUNT(*) > 0` clause
+to [prevent aggregate functions such as `MIN` and `MAX` from returning `NULL`](https://stackoverflow.com/questions/66527856/aggregate-functions-max-etc-return-null-instead-of-no-rows).
+
+Don't delete unused columns too early, but maybe after several months/releases, unused columns are
+still used by older versions, so deleting them breaks downgrading the core or importing a backup in
+an older version. Also don't change the column type, consider adding a new column with another name
+instead. Finally, never change column semantics, this is especially dangerous because the `STRICT`
+keyword doesn't help here.
+
+## Errors
+
+Delta Chat core mostly uses [`anyhow`](https://docs.rs/anyhow/) errors.
+When using [`Context`](https://docs.rs/anyhow/latest/anyhow/trait.Context.html),
+capitalize it but do not add a full stop as the contexts will be separated by `:`.
+For example:
+```
+.with_context(|| format!("Unable to trash message {msg_id}"))
+```
+
+All errors should be handled in one of these ways:
+- With `if let Err() =` (incl. logging them into `warn!()`/`err!()`).
+- With `.log_err().ok()`.
+- Bubbled up with `?`.
+
+`backtrace` feature is enabled for `anyhow` crate
+and `debug = 1` option is set in the test profile.
+This allows to run `RUST_BACKTRACE=1 cargo test`
+and get a backtrace with line numbers in resultified tests
+which return `anyhow::Result`.
+
+## Logging
+
+For logging, use `info!`, `warn!` and `error!` macros.
+Log messages should be capitalized and have a full stop in the end. For example:
+```
+info!(context, "Ignoring addition of {added_addr:?} to {chat_id}.");
+```
+
+Format anyhow errors with `{:#}` to print all the contexts like this:
+```
+error!(context, "Failed to set selfavatar timestamp: {err:#}.");
+```

+# Attaching a contact to a message
+
+Messengers MAY allow the user to attach a contact to a message
+in order to share it with the chat partner.
+The contact MUST be sent as a [vCard](https://datatracker.ietf.org/doc/html/rfc6350).
+
+The vCard MUST contain `EMAIL`,
+`FN` (display name),
+and `VERSION` (which version of the vCard standard you're using).
+If available, it SHOULD contain
+`REV` (current timestamp),
+`PHOTO` (avatar), and
+`KEY` (OpenPGP public key,
+in binary format,
+encoded with vanilla base64;
+note that this is different from the OpenPGP 'ASCII Armor' format).
+
+Example vCard:
+
+```
+BEGIN:VCARD
+VERSION:4.0
+EMAIL:alice@example.org
+FN:Alice Wonderland
+KEY:data:application/pgp-keys;base64,[Base64-data]
+PHOTO:data:image/jpeg;base64,[image in Base64]
+REV:20240418T184242Z
+END:VCARD
+```
+
+It is fine if messengers do include a full vCard parser
+and e.g. simply search for the line starting with `EMAIL`
+in order to get the email address.
