Steven Chanin a919269eb5 fix(skills/email/himalaya): document v1.2.0 folder.aliases syntax
The bundled himalaya skill documented folder aliases using a stale
TOML schema (`[accounts.NAME.folder.alias]`, singular) that himalaya
v1.2.0 silently ignores. The TOML parses without error, but the
alias resolver never reads the sub-section — every lookup then falls
through to the canonical folder name.

Source: in `pimalaya/core` (the `email-lib` crate himalaya v1.2.0
depends on, currently v0.27.0), `email/src/folder/config.rs` defines
`FolderConfig { aliases: Option<HashMap<String, String>>, ... }`
(plural, no `#[serde(rename)]`/`alias` aliases, no
`deny_unknown_fields`), and `account/config/mod.rs::get_folder_alias`
returns the input verbatim when no alias is found. So the singular
`alias` key deserializes to nothing and lookups silently fall
through.

On Gmail (where `sent` resolves to `[Gmail]/Sent Mail`, not `Sent`)
this means save-to-Sent fails *after* SMTP delivery already
succeeded, and `himalaya message send` exits non-zero. Any caller
(agent, script, user) that retries on that exit code will re-run
the entire send — including SMTP — producing duplicate emails to
recipients. Silent ignore + caller-level retry is significantly
worse than a config that just doesn't work.

This commit updates SKILL.md and references/configuration.md to the
v1.2.0 `folder.aliases.X` syntax (plural, dotted keys, directly
under the account section), adds a Gmail-specific block with the
`[Gmail]/Sent Mail`-style mapping, and adds notes on the failure
mode so future readers don't hit the same trap. SKILL.md version
bumped 1.0.0 → 1.1.0.

# Himalaya Configuration Reference
Configuration file location: `~/.config/himalaya/config.toml`
## Minimal IMAP + SMTP Setup
```toml
[accounts.default]
email = "user@example.com"
display-name = "Your Name"
default = true
# IMAP backend for reading emails
backend.type = "imap"
backend.host = "imap.example.com"
backend.port = 993
backend.encryption.type = "tls"
backend.login = "user@example.com"
backend.auth.type = "password"
backend.auth.raw = "your-password"
# SMTP backend for sending emails
message.send.backend.type = "smtp"
message.send.backend.host = "smtp.example.com"
message.send.backend.port = 587
message.send.backend.encryption.type = "start-tls"
message.send.backend.login = "user@example.com"
message.send.backend.auth.type = "password"
message.send.backend.auth.raw = "your-password"
# Folder aliases — required whenever server folder names differ
# from himalaya's canonical names. See "Folder Aliases" below.
folder.aliases.inbox = "INBOX"
folder.aliases.sent = "Sent"
folder.aliases.drafts = "Drafts"
folder.aliases.trash = "Trash"
```
## Password Options
### Raw password (testing only, not recommended)
```toml
backend.auth.raw = "your-password"
```
### Password from command (recommended)
```toml
backend.auth.cmd = "pass show email/imap"
# backend.auth.cmd = "security find-generic-password -a user@example.com -s imap -w"
```
### System keyring (requires keyring feature)
```toml
backend.auth.keyring = "imap-example"
```
Then run `himalaya account configure <account>` to store the password.
## Gmail Configuration
```toml
[accounts.gmail]
email = "you@gmail.com"
display-name = "Your Name"
default = true
backend.type = "imap"
backend.host = "imap.gmail.com"
backend.port = 993
backend.encryption.type = "tls"
backend.login = "you@gmail.com"
backend.auth.type = "password"
backend.auth.cmd = "pass show google/app-password"
message.send.backend.type = "smtp"
message.send.backend.host = "smtp.gmail.com"
message.send.backend.port = 587
message.send.backend.encryption.type = "start-tls"
message.send.backend.login = "you@gmail.com"
message.send.backend.auth.type = "password"
message.send.backend.auth.cmd = "pass show google/app-password"
# Gmail folder mapping. Without these, save-to-Sent fails after
# SMTP delivery succeeds (Gmail's Sent folder is `[Gmail]/Sent Mail`,
# not `Sent`), and `himalaya message send` exits non-zero. Any
# caller that retries on that error will re-run SMTP — duplicate
# emails to recipients. Always include this block for Gmail.
folder.aliases.inbox = "INBOX"
folder.aliases.sent = "[Gmail]/Sent Mail"
folder.aliases.drafts = "[Gmail]/Drafts"
folder.aliases.trash = "[Gmail]/Trash"
```
**Note:** Gmail requires an App Password if 2FA is enabled.
## iCloud Configuration
```toml
[accounts.icloud]
email = "you@icloud.com"
display-name = "Your Name"
backend.type = "imap"
backend.host = "imap.mail.me.com"
backend.port = 993
backend.encryption.type = "tls"
backend.login = "you@icloud.com"
backend.auth.type = "password"
backend.auth.cmd = "pass show icloud/app-password"
message.send.backend.type = "smtp"
message.send.backend.host = "smtp.mail.me.com"
message.send.backend.port = 587
message.send.backend.encryption.type = "start-tls"
message.send.backend.login = "you@icloud.com"
message.send.backend.auth.type = "password"
message.send.backend.auth.cmd = "pass show icloud/app-password"
```
**Note:** Generate an app-specific password at appleid.apple.com
## Folder Aliases
Map himalaya's canonical folder names (`inbox`, `sent`, `drafts`,
`trash`) to whatever the server actually calls them. Use the
v1.2.0 `folder.aliases.X` syntax (plural, dotted keys, directly
under `[accounts.NAME]`):
```toml
[accounts.default]
# ... other account config ...
folder.aliases.inbox = "INBOX"
folder.aliases.sent = "Sent"
folder.aliases.drafts = "Drafts"
folder.aliases.trash = "Trash"
```
The equivalent TOML sub-section form also works in v1.2.0:
```toml
[accounts.default.folder.aliases]
inbox = "INBOX"
sent = "Sent"
drafts = "Drafts"
trash = "Trash"
```
> **Don't use the singular `alias` form.** Pre-v1.2.0 docs showed
> `[accounts.NAME.folder.alias]` (singular). v1.2.0 silently
> ignores that sub-section — TOML parses without error, but the
> alias resolver never reads it. Every lookup then falls through
> to the canonical name. On Gmail (where `sent` is actually
> `[Gmail]/Sent Mail`) this means save-to-Sent fails *after* SMTP
> delivery succeeds, and `himalaya message send` exits non-zero.
> Any caller (agent, script, user) that retries on that error
> code will re-run the send — including SMTP — producing duplicate
> emails to recipients. Always use `folder.aliases.X` (plural).
## Multiple Accounts
```toml
[accounts.personal]
email = "personal@example.com"
default = true
# ... backend config ...
[accounts.work]
email = "work@company.com"
# ... backend config ...
```
Switch accounts with `--account`:
```bash
himalaya --account work envelope list
```
## Notmuch Backend (local mail)
```toml
[accounts.local]
email = "user@example.com"
backend.type = "notmuch"
backend.db-path = "~/.mail/.notmuch"
```
## OAuth2 Authentication (for providers that support it)
```toml
backend.auth.type = "oauth2"
backend.auth.client-id = "your-client-id"
backend.auth.client-secret.cmd = "pass show oauth/client-secret"
backend.auth.access-token.cmd = "pass show oauth/access-token"
backend.auth.refresh-token.cmd = "pass show oauth/refresh-token"
backend.auth.auth-url = "https://provider.com/oauth/authorize"
backend.auth.token-url = "https://provider.com/oauth/token"
```
## Additional Options
### Signature
```toml
[accounts.default]
signature = "Best regards,\nYour Name"
signature-delim = "-- \n"
```
### Downloads directory
```toml
[accounts.default]
downloads-dir = "~/Downloads/himalaya"
```
### Editor for composing
Set via environment variable:
```bash
export EDITOR="vim"
```
