feat: add YAML frontmatter, bitcoin-conventions skill, path rules, and Gitea CI

- Added YAML frontmatter to all 8 polish-* skills and sweep skill
  so Claude can auto-invoke them
- New bitcoin-conventions skill with PROUX UX methodology, sats display,
  address validation, Tor preferences, Lightning patterns
- Path-specific rules for containers (security hardening) and frontend
  (Vue/glassmorphism conventions)
- Gitea Actions: nightly security review and weekly dependency audit

+# Container Security Rules (Archipelago)
+
+- `readonly_root: true` always — containers must not write to their root filesystem
+- Drop ALL capabilities, add only what's required (`--cap-drop=ALL --cap-add=...`)
+- Run as non-root user (UID > 1000): `--user 1001:1001`
+- Set `--security-opt=no-new-privileges:true`
+- Pin image versions by SHA256 digest, never use `:latest` tag
+- Mount secrets as read-only files, never pass as environment variables when possible
+- Set memory and CPU limits on all containers
+- Use `--network=none` unless network access is required

+# Frontend Rules (Archipelago)

+- Always use `<script setup lang="ts">` in Vue components
+- Global CSS classes go in `style.css`, never inline Tailwind utilities
+- Use `.glass-button` for ALL buttons — `.gradient-button` is BANNED
+- Use Pinia stores for shared state, never provide/inject for cross-component data
+- Every async view needs: loading state, empty state, and error state
+- Trim all text inputs before submission
+- Disable submit buttons during async operations
+- Use `errorMessage` ref pattern for user-visible errors, not just console.log

+name: bitcoin-conventions
+description: Bitcoin development conventions for Archipelago. Covers sats display (integers, never float), address type detection, Tor/onion endpoint preference, Bitcoin RPC error handling, and Lightning patterns. Use when working with Bitcoin amounts, addresses, RPC calls, Lightning channels, or onion services.
+---
+
+# Bitcoin Development Conventions
+
+## Critical Rules
+
+- **NEVER use floating point for Bitcoin amounts.** Sats are always `u64` (Rust) or `BigInt`/integer (TypeScript).
+- **NEVER log private keys, seeds, or mnemonics.** Not even at debug/trace level.
+- **Prefer Tor/onion endpoints** for all Bitcoin network services when available.
+
+## Amount Display
+
+### Rust
+```rust
+// Amount is always in sats as u64
+pub fn format_sats(sats: u64) -> String {
+    if sats >= 100_000_000 {
+        let btc = sats / 100_000_000;
+        let remainder = sats % 100_000_000;
+        if remainder == 0 {
+            format!("{} BTC", btc)
+        } else {
+            format!("{}.{:08} BTC", btc, remainder)
+        }
+    } else {
+        format!("{} sats", sats)
+    }
+}
+```
+
+### TypeScript
+```typescript
+// Never: amount * 0.00000001
+// Always: integer arithmetic or BigInt
+function formatSats(sats: number): string {
+  if (sats >= 100_000_000) {
+    const btc = Math.floor(sats / 100_000_000)
+    const remainder = sats % 100_000_000
+    return remainder === 0 ? `${btc} BTC` : `${btc}.${String(remainder).padStart(8, '0')} BTC`
+  }
+  return `${sats.toLocaleString()} sats`
+}
+```
+
+## Address Types
+
+Detect and display address type:
+- `1...` — P2PKH (Legacy)
+- `3...` — P2SH (SegWit-compatible)
+- `bc1q...` — P2WPKH (Native SegWit)
+- `bc1p...` — P2TR (Taproot)
+
+Always validate addresses before any operation. Use network-appropriate validation (mainnet `bc1`, testnet `tb1`, regtest `bcrt1`).
+
+## Bitcoin RPC Error Handling
+
+```rust
+match rpc_response.error {
+    Some(err) => {
+        // Standard Bitcoin Core RPC error codes
+        match err.code {
+            -1 => /* miscellaneous error */,
+            -5 => /* invalid address or key */,
+            -6 => /* insufficient funds */,
+            -25 => /* transaction verification failed */,
+            -26 => /* transaction rejected by policy */,
+            -27 => /* transaction already in chain */,
+            -28 => /* client still warming up */,
+            _ => /* unknown error */,
+        }
+    }
+    None => { /* success */ }
+}
+```
+
+Always set explicit timeouts on RPC calls (10s default, 30s for heavy operations like `rescanblockchain`).
+
+## Tor/Onion Preferences
+
+When configuring Bitcoin services:
+1. Check for Tor SOCKS proxy (default: `127.0.0.1:9050`)
+2. If available, route Bitcoin P2P and RPC through Tor
+3. Prefer `.onion` endpoints for block explorers, electrum servers
+4. Set `proxy=127.0.0.1:9050` in `bitcoin.conf`
+5. Set `onlynet=onion` for maximum privacy (if full Tor mode)
+
+## Lightning (LND/CLN) Patterns
+
+### BOLT11 Invoice handling
+- Always validate invoice before displaying to user
+- Show: amount, description, expiry, destination pubkey
+- Never auto-pay without user confirmation
+
+### Channel States
+Display human-readable channel state:
+- `PENDING_OPEN` → "Opening..."
+- `OPEN` → "Active"
+- `PENDING_CLOSE` / `FORCE_CLOSING` → "Closing..."
+- `CLOSED` → "Closed"
+
+### Macaroon handling
+- Never log macaroon contents
+- Store with restrictive permissions (0600)
+- Use read-only macaroon for queries, admin macaroon only for mutations
+
+## Container Images for Bitcoin Services
+
+- **Always pin by SHA256 digest**, never by tag alone
+- Example: `docker.io/lnzap/lnd@sha256:abc123...` not `lnzap/lnd:latest`
+- Verify image signatures when available (cosign/notary)
